XSetWMProtocols(3)			  XLIB FUNCTIONS		       XSetWMProtocols(3)

NAME
       XSetWMProtocols, XGetWMProtocols - set or read a window's WM_PROTOCOLS property

SYNTAX
       Status XSetWMProtocols(Display *display, Window w, Atom *protocols, int count);

       Status XGetWMProtocols(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.

       count_return
		 Returns the number of protocols in the list.

       protocols Specifies the list of protocols.

       protocols_return
		 Returns the list of protocols.

DESCRIPTION
       The XSetWMProtocols 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, XSetWMProtocols 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, XSetWMProtocols
       returns a zero status.  Otherwise, it returns a nonzero status.

       XSetWMProtocols can generate BadAlloc and BadWindow errors.

       The XGetWMProtocols 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, XGetWMProtocols sets the proto-
       cols_return argument to a list of atoms, sets the count_return argument to the number of
       elements in the list, and returns a nonzero status.  Otherwise, it sets neither of the
       return arguments and returns a zero status.  To release the list of atoms, use XFree.

       XGetWMProtocols can generate a BadWindow 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
       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.
