E.g. "dcopstart kedit" might return "kedit-29322". An +exit-code of '0' means success. An exit-code of '1' means error, the error +msg is printed to stderr and no data is printed to stdout. + + +dcopfind [-l] [-a] <app-id> [<object-id> [<select_func> [args]]] + +Finds an existing DCOP application/object. The select_func can be used to +select a specific single instance out of many based on some criteria. +<app-id> and <object-id> may end with a '*' as wildcard. + +The function returns a <app-object-id> to stdout in the form + + "DCOPRef(<app-id>, <object-id>)" + +if an object is found and returns an exit-code of '0'. +If no object is found, nothing is written to stdout and the exit-code is '1'. + +With the -a option it prints out "<app-id>" instead of a DCOPRef. + +With the -l option it calls "dcopstart <app-id>" if no object is found, +stripping off any wildcard from the <app-id>. If the dcopstart command is +successful the find command is repeated, if the dcopstart command fails, an +error message is printed to stderr and the command exits with exit-code '2'. + +The default selection criteria is "any". Applications can declare their own +select_func as they see fit, e.g. konqueror could declare +"isDoingProtocol(QString protocol)" and then the following command would +select a konqueror mainwindow that is currently handling the help-protocol: + + "dcopfind 'konqueror*' 'konqueror-mainwindow*' 'isDoingProtocol(QString +protocol)' help" + + +dcop <dcopref> <function> args + +In addtion to the current syntax of + + dcop <appid> <object> <function> args + +you will now also be able to use <dcopref> to make calls with <dcopref> being +"DCOPRef(<appid>, <objectid>)" as returned by dcopfind. + +Additional utilities: + + "dcopref <appid> <object>" + +Creates a DCOPRef from appid and object. + + + "dcopclient <dcopref>" + +Extracts the appid from dcopref. + + + "dcopobject <dcopref>" + +Extracts the object from dcopref. + + |
