ARGUMENTS

17       display   Specifies the connection to the X server.
18

23
24       protocols Specifies the list of protocols.

DESCRIPTION

30       The XSetWMProtocols function replaces the WM_PROTOCOLS property on the
31       specified window with the list of atoms specified by the protocols
32       argument.  If the property does not already exist, XSetWMProtocols sets
33       the WM_PROTOCOLS property on the specified window to the list of atoms
34       specified by the protocols argument.  The property is stored with a
35       type of ATOM and a format of 32.  If it cannot intern the WM_PROTOCOLS
36       atom, XSetWMProtocols returns a zero status.  Otherwise, it returns a
37       nonzero status.
38
39       XSetWMProtocols can generate BadAlloc and BadWindow errors.
40
41       The XGetWMProtocols function returns the list of atoms stored in the
42       WM_PROTOCOLS property on the specified window.  These atoms describe
43       window manager protocols in which the owner of this window is willing
44       to participate.  If the property exists, is of type ATOM, is of format
45       32, and the atom WM_PROTOCOLS can be interned, XGetWMProtocols sets the
46       protocols_return argument to a list of atoms, sets the count_return
47       argument to the number of elements in the list, and returns a nonzero
48       status.  Otherwise, it sets neither of the return arguments and returns
49       a zero status.  To release the list of atoms, use XFree.
50
51       XGetWMProtocols can generate a BadWindow error.

PROPERTIES

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

DIAGNOSTICS

60       BadAlloc  The server failed to allocate the requested resource or
61                 server memory.
62
63       BadWindow A value for a Window argument does not name a defined Window.
