XSetWMProtocols(3X11)         SDK X11 R4.11MU05        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, protocolsreturn, countreturn)
             Display *display;
             Window w;
             Atom **protocolsreturn;
             int *countreturn;

ARGUMENTS
       display   Specifies the connection to the X server.

       count     Specifies the number of protocols in the list.

       countreturn
                 Returns the number of protocols in the list.

       protocols Specifies the list of protocols.

       protocolsreturn
                 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.

       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.
