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 can-
       not 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 win-
       dow.  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.
