Description
The 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, 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, returns a zero sta-
tus. Otherwise, it returns a non-zero status.
can generate and errors.
The 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, sets the protocols_return argument to a list of atoms, sets the count_return argument to the number of
elements in list, and returns a a non-zero status. Otherwise, it sets neither of the return arguments and returns a zero status. To
release the list of atom, use
can generate a error.
Properties
