XSetCommand(3)			XLIB FUNCTIONS			XSetCommand(3)

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

       int XSetCommand(Display *display, Window w, char **argv, int argc);

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

       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 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
       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.
       Otherwise, or if any other error is encountered, it returns a zero sta‐
       tus.  If the data returned by the server is in the Latin Portable Char‐
       acter Encoding, then the returned strings are in the Host Portable
       Character Encoding.  Otherwise, the result is implementation-dependent.
       To free the memory allocated to the string list, use XFreeStringList.

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

       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.
