(Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price.

You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program.

Schindelin + +What is it? +----------- + +VNC is a set of programs using the RFB (Remote Frame Buffer) protocol. They +are designed to "export" a frame buffer via net (if you don't know VNC, I +suggest you read "Basics" below). It is already in wide use for +administration, but it is not that easy to program a server yourself. + +This has been changed by LibVNCServer. + +There are two examples included: + - example, a shared scribble sheet + - pnmshow, a program to show PNMs (pictures) over the net. + +The examples are not too well documented, but easy straight forward and a +good starting point. + +Try example: it outputs on which port it listens (default: 5900), so it is +display 0. To view, call + vncviewer :0 +You should see a sheet with a gradient and "Hello World!" written on it. Try +to paint something. Note that everytime you click, there is some bigger blot. +The size depends on the mouse button you click. Open a second vncviewer with +the same parameters and watch it as you paint in the other window. This also +works over internet. You just have to know either the name or the IP of your +machine. Then it is + vncviewer machine.where.example.runs.com:0 +or similar for the remote client. Now you are ready to type something. Be sure +that your mouse sits still, because everytime the mouse moves, the cursor is +reset! If you are done with that demo, just press Escape in the viewer. Note +that the server still runs, even if you closed both windows. When you +reconnect now, everything you painted and wrote is still there. So you press +"Page Up" for a blank page. + +The demo pnmshow is much simpler: you either provide a filename as argument +or pipe a file through stdin. Note that the file has to be a raw pnm/ppm file, +i.e. a truecolour graphics. Only the Escape key is implemented. This may be +the best starting point if you want to learn how to use LibVNCServer. You +are confronted with the fact that the bytes per pixel can only be 8, 16 or 32. + +How to use +---------- + +To make a server, you just have to initialise a server structure using the +function rfbDefaultScreenInit, like + rfbScreenInfoPtr rfbScreen = + rfbGetScreen(argc,argv,width,height,8,3,bpp); +where byte per pixel should be 1, 2 or 4. If performance doesn't matter, +you may try bpp=3 (internally one cannot use native data types in this +case; if you want to use this, look at pnmshow24). + + +You then can set hooks and io functions (see below) or other +options (see below). + +And you allocate the frame buffer like this: + rfbScreen->frameBuffer = (char*)malloc(width*height*bpp); + +After that, you initialize the server, like + rfbInitServer(rfbScreen); + +You can use a blocking event loop, a background (pthread based) event loop, +or implement your own using the rfbProcessEvents function. + +Making it interactive +--------------------- + +Input is handled by IO functions (see below). + +Whenever you change something in the frame buffer, call rfbMarkRectAsModified. +You should make sure that the cursor is not drawn before drawing yourself +by calling rfbUndrawCursor. You can also draw the cursor using rfbDrawCursor, +but it hardly seems necessary. For cursor details, see below. + +Utility functions +----------------- + +Whenever you draw something, you have to call + rfbMarkRectAsModified(screen,x1,y1,x2,y2). +This tells LibVNCServer to send updates to all connected clients. + +Before you draw something, be sure to call + rfbUndrawCursor(screen). +This tells LibVNCServer to hide the cursor. +Remark: There are vncviewers out there, which know a cursor encoding, so +that network traffic is low, and also the cursor doesn't need to be +drawn the cursor everytime an update is sent. LibVNCServer handles +all the details. Just set the cursor and don't bother any more. + +To set the mouse coordinates (or emulate mouse clicks), call + defaultPtrAddEvent(buttonMask,x,y,cl); +However, this works only if your client doesn't do local cursor drawing. There +is no way (to my knowledge) to set the pointer of a client via RFB protocol. +IMPORTANT: do this at the end of your function, because this actually draws +the cursor if no cursor encoding is active. + +What is the difference between rfbScreenInfoPtr and rfbClientPtr? +----------------------------------------------------------------- + +The rfbScreenInfoPtr is a pointer to a rfbScreenInfo structure, which +holds information about the server, like pixel format, io functions, +frame buffer etc. + +The rfbClientPtr is a pointer to an rfbClientRec structure, which holds +information about a client, like pixel format, socket of the +connection, etc. + +A server can have several clients, but needn't have any. So, if you +have a server and three clients are connected, you have one instance +of a rfbScreenInfo and three instances of rfbClientRec's. + +The rfbClientRec structure holds a member + rfbScreenInfoPtr screen +which points to the server and a member + rfbClientPtr next +to the next client. + +The rfbScreenInfo structure holds a member + rfbClientPtr rfbClientHead +which points to the first client. + +So, to access the server from the client structure, you use client->screen. +To access all clients from a server, get screen->rfbClientHead and +iterate using client->next. + +If you change client settings, be sure to use the provided iterator + rfbGetClientIterator(rfbScreen) +with + rfbClientIteratorNext(iterator) +and + rfbReleaseClientIterator +to prevent thread clashes. + +Other options +------------- + +These options have to be set between rfbGetScreen and rfbInitServer. + +If you already have a socket to talk to, just set rfbScreen->inetdSock +(originally this is for inetd handling, but why not use it for your purpose?). + +To also start an HTTP server (running on port 5800+display_number), you have +to set rfbScreen->httpdDir to a directory containing vncviewer.jar and +index.vnc (like the included "classes" directory). + +Hooks and IO functions +---------------------- + +There exist the following IO functions as members of rfbScreen: +kbdAddEvent, kbdReleaseAllKeys, ptrAddEvent and setXCutText + +kbdAddEvent(Bool down,KeySym key,rfbClientPtr cl) + is called when a key is pressed. +kbdReleaseAllKeys(rfbClientPtr cl) + is not called at all (maybe in the future). +ptrAddEvent(int buttonMask,int x,int y,rfbClientPtr cl) + is called when the mouse moves or a button is pressed. + WARNING: if you want to have proper cursor handling, call + defaultPtrAddEvent(buttonMask,x,y,cl) + in your own function. This sets the coordinates of the cursor. +setXCutText(char* str,int len,rfbClientPtr cl) + is called when the selection changes. + +There are only two hooks: +newClientHook(rfbClientPtr cl) + is called when a new client has connected. +displayHook + is called just before a frame buffer update is sent. + +You can also override the following methods: +getCursorPtr(rfbClientPtr cl) + This could be used to make an animated cursor (if you really want ...) +setTranslateFunction(rfbClientPtr cl) + If you insist on colour maps or something more obscure, you have to + implement this. Default is a trueColour mapping. + +Cursor handling +--------------- + +The screen holds a pointer + rfbCursorPtr cursor +to the current cursor. Whenever you set it, remember that any dynamically +created cursor (like return value from rfbMakeXCursor) is not free'd! + +The rfbCursor structure consists mainly of a mask and a source. The mask +describes, which pixels are drawn for the cursor (a cursor needn't be +rectangular). The source describes, which colour those pixels should have. + +The standard is an XCursor: a cursor with a foreground and a background +colour (stored in backRed,backGreen,backBlue and the same for foreground +in a range from 0-0xffff). Therefore, the arrays "mask" and "source" +contain pixels as single bits stored in bytes in MSB order. The rows are +padded, such that each row begins with a new byte (i.e. a 10x4 +cursor's mask has 2x4 bytes, because 2 bytes are needed to hold 10 bits). + +It is however very easy to make a cursor like this: + +char* cur=" " + " xx " + " x " + " "; +char* mask="xxxx" + "xxxx" + "xxxx" + "xxx "; +rfbCursorPtr c=rfbMakeXCursor(4,4,cur,mask); + +You can even set "mask" to NULL in this call and LibVNCServer will calculate +a mask for you (dynamically, so you have to free it yourself). + +There is also an array named "richSource" for colourful cursors. They have +the same format as the frameBuffer (i.e. if the server is 32 bit, +a 10x4 cursor has 4x10x4 bytes). + +History +------- + +LibVNCServer is based on Tridia VNC and OSXvnc, which in turn are based on +the original code from ORL/AT&T. + +When I began hacking with computers, my first interest was speed. So, when I +got around assembler, I programmed the floppy to do much of the work, because +it's clock rate was higher than that of my C64. This was my first experience +with client/server techniques. + +When I came around Xwindows (much later), I was at once intrigued by the +elegance of such connectedness between the different computers. I used it +a lot - not the least priority lay on games. However, when I tried it over +modem from home, it was no longer that much fun. + +When I started working with ASP (Application Service Provider) programs, I +tumbled across Tarantella and Citrix. Being a security fanatic, the idea of +running a server on windows didn't appeal to me, so Citrix went down the +basket. However, Tarantella has it's own problems (security as well as the +high price). But at the same time somebody told me about this "great little +administrator's tool" named VNC. Being used to windows programs' sizes, the +surprise was reciprocal inverse to the size of VNC! + +At the same time, the program "rdesktop" (a native Linux client for the +Terminal Services of Windows servers) came to my attention. There where even +works under way to make a protocol converter "rdp2vnc" out of this. However, +my primary goal was a slow connection and rdp2vnc could only speak RRE +encoding, which is not that funny with just 5kB/s. Tim Edmonds, the original +author of rdp2vnc, suggested that I adapt it to Hextile Encoding, which is +better. I first tried that, but had no success at all (crunchy pictures). + +Also, I liked the idea of an HTTP server included and possibly other +encodings like the Tight Encodings from Const Kaplinsky. So I started looking +for libraries implementing a VNC server where I could steal what I can't make. +I found some programs based on the demo server from AT&T, which was also the +basis for rdp2vnc (can only speak Raw and RRE encoding). There were some +rumors that GGI has a VNC backend, but I didn't find any code, so probably +there wasn't a working version anyway. + +All of a sudden, everything changed: I read on freshmeat that "OSXvnc" was +released. I looked at the code and it was not much of a problem to work out +a simple server - using every functionality there is in Xvnc. It became clear +to me that I *had* to build a library out of it, so everybody can use it. +Every change, every new feature can propagate to every user of it. + +It also makes everything easier: + You don't care about the cursor, once set (or use the standard cursor). +You don't care about those sockets. You don't care about encodings. +You just change your frame buffer and inform the library about it. Every once +in a while you call rfbProcessEvents and that's it. + +Basics +------ + +VNC (Virtual network computing) works like this: You set up a server and can +connect to it via vncviewers. The communication uses a protocol named RFB +(Remote Frame Buffer). If the server supports HTTP, you can also connect +using a java enabled browser. In this case, the server sends back a +vncviewer applet with the correct settings. + +There exist several encodings for VNC, which are used to compress the regions +which have changed before they are sent to the client. A client need not be +able to understand every encoding, but at least Raw encoding. Which encoding +it understands is negotiated by the RFB protocol. + +The following encodings are known to me: +Raw, RRE, CoRRE, Hextile, CopyRect from the original AT&T code and +Tight, ZLib, LastRect, XCursor, RichCursor from Const Kaplinsky et al. + +If you are using a modem, you want to try the "new" encodings. Especially +with my 56k modem I like ZLib or Tight with Quality 0. In my tests, it even +beats Tarantella. + +There is the possibility to set a password, which is also negotiated by the +RFB protocol, but IT IS NOT SECURE. Anybody sniffing your net can get the +password. You really should tunnel through SSH. + +Windows or: why do you do that to me? +-------------------------------------------- + +If you love products from Redmod, you better skip this paragraph. +I am always amazed how people react whenever Microsoft(tm) puts in some +features into their products which were around for a long time. Especially +reporters seem to not know dick about what they are reporting about! But +what is everytime annoying again, is that they don't do it right. Every +concept has it's new name (remember what enumerators used to be until +Mickeysoft(tm) claimed that enumerators are what we thought were iterators. +Yeah right, enumerators are also containers. They are not separate. Muddy.) + +There are three packages you want to get hold of: zlib, jpeg and pthreads. +The latter is not strictly necessary, but when you put something like this +into your source: + +#define MUTEX(s) + struct { + int something; + MUTEX(latex); + } + +Microsoft's C++ compiler doesn't do it. It complains that this is an error. + +You can find the packages at +http://www.gimp.org/win32/extralibs-dev-20001007.zip + +Thanks go to all the GIMP team! + +What are those other targets in the Makefile? +--------------------------------------------- + +OSXvnc-server is the original OSXvnc adapted to use the library, which was in +turn adapted from OSXvnc. As you easily can see, the OSX dependend part is +minimal. + +storepasswd is the original program to save a vnc style password in a file. +Unfortunately, authentication as every vncviewer speaks it means the server +has to know the plain password. You really should tunnel via ssh or use +your own PasswordCheck to build a PIN/TAN system. + +sratest is a test unit. Run it to assert correct behaviour of sraRegion. I +wrote this to test my iterator implementation. + +blooptest is a test of pthreads. It is just the example, but with a background +loop to hunt down thread lockups. + +pnmshow24 is like pnmshow, but it uses 3 bytes/pixel internally, which is not +as efficient as 4 bytes/pixel for translation, because there is no native data +type of that size, so you have to memcpy pixels and be real cautious with +endianness. Anyway, it works. + +fontsel is a test for rfbSelectBox and rfbLoadConsoleFont. If you have Linux +console fonts, you can browse them via VNC. Directory browsing not implemented +yet :-( + +Why I don't feel bad about GPL +------------------------------ + +At the beginning of this projects I would have liked to make it a BSD +license. However, it is based on plenty of GPL'ed code, so it has to be +a GPL. I hear BeeGee complaining: "but that's invasive, every derivative +work, even just linking, makes my software GPL!" + +Yeah. That's right. It is because there are nasty jarheads out there who +would take anybody's work and claim it their own, selling it for much too +much money, stealing freedom and innovation from others, saying they were +the maintainers of innovation, lying, making money with that. + +The people at AT&T worked really well to produce something as clean and lean +as VNC. The managers decided that for their fame, they would release the +program for free. But not only that! They realized that by releasing also +the code for free, VNC would become an evolving little child, conquering +new worlds, making it's parents very proud. As well they can be! To protect +this innovation, they decided to make it GPL, not BSD. The principal +difference is: You can make closed source programs deriving from BSD, not +from GPL. You have to give proper credit with both. + +Now, why not BSD? Well, imagine your child being some famous actor. Along +comes a manager who exploits your child exclusively, that is: nobody else +can profit from the child, it itself included. Got it? + +What reason do you have now to use this library commercially? + +Several: You don't have to give away your product. Then you have effectively +circumvented the GPL, because you have the benefits of other's work and you +don't give back anything and you will be in hell for that. In fact, this +library, as my other projects, is a payback for all the free software I can +use (and sometimes, make better). For example, just now, I am using XEmacs +on top X11, all running under Linux. + +Better: Use a concept like MySQL. This is free software, however, they make +money with it. If you want something implemented, you have the choice: +Ask them to do it (and pay a fair price), or do it yourself, normally giving +back your enhancements to the free world of computing. + +Learn from it: If you like the style this is written, learn how to imitate +it. If you don't like the style, learn how to avoid those things you don't +like. I learnt so much, just from looking at code like Linux, XEmacs, +LilyPond, STL, etc. + +License +------- + +This program is free software; you can redistribute it and/or +modify it under the terms of the GNU General Public License +as published by the Free Software Foundation; either version 2 +of the License, or (at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

While this is happening, cursorIsDrawn must be FALSE so + that PushPixels doesn't think it has to remove the cursor first. + Obviously cursorIsDrawn is set to TRUE afterwards. + + Another problem we face is that drawing routines sometimes cause a + framebuffer update to be sent to the RFB client. When the RFB client is + already waiting for a framebuffer update and some drawing to the + framebuffer then happens, the drawing routine sees that the client is + ready, so it calls rfbSendFramebufferUpdate. If the cursor is not drawn + at this stage, it must be put up, and so rfbSpriteRestoreCursor is + called. However, if the original drawing routine was actually called + from within rfbSpriteRestoreCursor or rfbSpriteRemoveCursor we don't + want this to happen.
