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



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

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

       Status XGetCommand(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 pro-
       gram.)  If the strings are not in the Host Portable Character Encod-
       ing, 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, 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 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 Win-
		 dow.
