XSetWMProtocols(3X11)	       XLIB FUNCTIONS		XSetWMProtocols(3X11)



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

SYNTAX
  Status XSetWMProtocols(display, w, protocols, count)
	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.

  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 argu-
  ment.	 If the property does not already exist, XSetWMProtocols sets the
  WM_PROTOCOLS property on the specified window to the list of atoms speci-
  fied 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, XSetWMPro-
  tocols 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 partici-
  pate.	 If the property exists, is of type ATOM, is of format 32, and the
  atom WM_PROTOCOLS can be interned, XGetWMProtocols sets the
  protocols_return argument to a list of atoms, sets the count_return argu-
  ment 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.
