XSetWMProtocols(3X11)       X Version 11(Release 5)       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
      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
      protocols_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.

XSetWMProtocols(3X11)       X Version 11(Release 5)       XSetWMProtocols(3X11)


      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.
