NAME

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

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.
