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.

protocols Specifies the list of protocols.
protocols_return

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.
