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


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

       Status   XGetWMProtocols(Display   *display,   Window   w,  Atom  **protocols_return,  int


       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.
