	  Display *display;
	  Window w;
	  Atom *protocols;
	  int count;

       Status XGetWMProtocols(display, w, protocols_return, count_return)
	  Display *display;
	  Window w;
	  Atom **protocols_return;
	  int *count_return;

Arguments
       display	 Specifies the connection to the X server.

       count	 Specifies the number of protocols in the list.

Description
       The function replaces the WM_PROTOCOLS property on the specified window with the list of atoms specified by the protocols argument.  If the
       property does not already exist, sets the WM_PROTOCOLS property on the specified window to the list of atoms specified by the protocols
       argument.  The property is stored with a type of ATOM and a format of 32.  If it cannot intern the WM_PROTOCOLS atom, returns a zero sta-
       tus.  Otherwise, it returns a non-zero status.

       can generate and errors.

       The function returns the list of atoms stored in the WM_PROTOCOLS property on the specified window.  These atoms describe window manager
       protocols in which the owner of this window is willing to participate.  If the property exists, is of type ATOM, is of format 32, and the
       atom WM_PROTOCOLS can be interned, sets the protocols_return argument to a list of atoms, sets the count_return argument to the number of
       elements in list, and returns a a non-zero status.  Otherwise, it sets neither of the return arguments and returns a zero status.  To
       release the list of atom, use

       can generate a error.

Properties
       WM_PROTOCOLS
		 List of atoms that identify the communications protocols between the client and window manager in which the client is willing to
		 participate.

Diagnostics
       The server failed to allocate the requested resource or server memory.

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