XSetCommand(3X11)        XLIB FUNCTIONS         XSetCommand(3X11)


     XSetCommand, XGetCommand - set or read a window's WM_COMMAND


     int XSetCommand(Display *display, Window w, char **argv, int

     Status XGetCommand(Display *display, Window w, char
          ***argv_return, int *argc_return);


     argc      Specifies the number of arguments.

               Returns the number of arguments returned.

     argv      Specifies the application's argument list.

               Returns the application's argument list.

     display   Specifies the connection to the X server.

     w         Specifies the window.


     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

     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 contain the
     string list, XGetCommand fills in the argv_return and
     argc_return arguments and returns a nonzero status. Other-
     wise, 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 Encod-
     ing. Otherwise, the result is implementation-dependent. To
     free the memory allocated to the string list, use XFreeS-


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