XSetCommand(3X11) XSetCommand(3X11) NAME XSetCommand, XGetCommand - set or read a window's WM_COMMAND property SYNOPSIS XSetCommand(display, w, argv, argc) Display *display; Window w; char **argv; int argc; Status XGetCommand(display, w, argv_return, argc_return) Display *display; Window w; char ***argv_return; int *argc_return; ARGUMENTS Specifies the number of arguments. Returns the number of arguments re- turned. Specifies the application's argument list. Returns the appli- cation's argument list. Specifies the connection to the X server. Specifies the window. DESCRIPTION The XSetCommand function sets the command and arguments used to invoke the application. (Typically, argv is the argv array of your main pro- gram.) If the strings are not in the Host Portable Character Encoding, the result is implementation dependent. XSetCommand can generate BadAlloc and BadWindow errors. The XGetCommand function reads the WM_COMMAND property from the speci- fied window and returns a string list. If the WM_COMMAND property ex- ists, it is of type STRING and format 8. If sufficient memory can be allocated to contain the string list, XGetCommand fills in the argv_re- turn and argc_return arguments and returns a nonzero status. Otherwise, it returns a zero status. If the data returned by the server is in the Latin Portable Character Encoding, then the returned strings are in the Host Portable Character Encoding. Otherwise, the result is implementa- tion dependent. To free the memory allocated to the string list, use XFreeStringList. PROPERTIES The command and arguments, null-separated, used to invoke the applica- tion. DIAGNOSTICS The server failed to allocate the requested resource or server memory. A value for a Window argument does not name a defined Window.
