XSetWMProtocols(3) XLIB FUNCTIONS XSetWMProtocols(3)
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_re-
turn, 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 ar-
gument. 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 ar-
gument 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 be-
tween 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.
