NAME
XSetCloseDownMode, XKillClient - control clients
SYNTAX
int
XSetCloseDownMode(Display * display, int close_mode);
int
XKillClient(Display * display, XID resource);
ARGUMENTS
- close_mode
- Specifies the client close-down mode. You can pass
DestroyAll, RetainPermanent, or RetainTemporary.
- display
- Specifies the connection to the X server.
- resource
- Specifies any resource associated with the client that you
want to destroy or AllTemporary.
DESCRIPTION
The
XSetCloseDownMode defines what will happen to the client's resources
at connection close. A connection starts in
DestroyAll mode. For
information on what happens to the client's resources when the close_mode
argument is
RetainPermanent or
RetainTemporary, see section 2.6.
XSetCloseDownMode can generate a
BadValue error.
The
XKillClient function forces a close down of the client that created
the resource if a valid resource is specified. If the client has already
terminated in either
RetainPermanent or
RetainTemporary mode,
all of the client's resources are destroyed. If
AllTemporary is
specified, the resources of all clients that have terminated in
RetainTemporary are destroyed (see section 2.5). This permits
implementation of window manager facilities that aid debugging. A client can
set its close-down mode to
RetainTemporary. If the client then crashes,
its windows would not be destroyed. The programmer can then inspect the
application's window tree and use the window manager to destroy the zombie
windows.
XKillClient can generate a
BadValue error.
DIAGNOSTICS
- BadValue
- Some numeric value falls outside the range of values
accepted by the request. Unless a specific range is specified for an
argument, the full range defined by the argument's type is accepted. Any
argument defined as a set of alternatives can generate this error.
