XSetCommand(3X11)

NAME
       XSetCommand, XGetCommand - set or read a window's WM_COM-
       MAND property

SYNTAX
       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
       argc      Specifies the number of arguments.

       argc_return
                 Returns the number of arguments returned.

       argv      Specifies the application's argument list.

       argv_return
                 Returns the application's argument list.

       display   Specifies the connection to the X server.

       w         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 program.)  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 specified window and returns a string list.  If
       the WM_COMMAND property exists, it is of type STRING and
       format 8.  If sufficient memory can be allocated to con-
       tain the string list, XGetCommand fills in the argv_return
       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 Charac-
       ter Encoding.  Otherwise, the result is implementation-
       dependent.  To free the memory allocated to the string
       list, use XFreeStringList.

PROPERTIES
       WM_COMMAND
                 The command and arguments, null-separated, used
                 to invoke the application.

DIAGNOSTICS
       BadAlloc  The server failed to allocate the requested
                 resource or server memory.

       BadWindow A value for a Window argument does not name a
                 defined Window.
