XSetWMProtocols(3)              XLIB FUNCTIONS              XSetWMProtocols(3)

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

       Status XSetWMProtocols(Display *display, Window w, Atom *protocols, int

       Status XGetWMProtocols(Display *display, Window w, Atom **proto-
              cols_return, int *count_return);

       display   Specifies the connection to the X server.

       count     Specifies the number of protocols in the list.

                 Returns the number of protocols in the list.

       protocols Specifies the list of protocols.

                 Returns the list of protocols.

       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.

                 List of atoms that identify the communications protocols
                 between the client and window manager in which the client is
                 willing to participate.

       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.
