XSetCloseDownMode(3)                                      XSetCloseDownMode(3)




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 Destroy-
                 All, 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 speci-
       fied, the resources of all clients that have terminated in RetainTempo-
       rary 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.
