NAME

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

SYNTAX

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

       Status XGetWMProtocols(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.

       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.
