XtAppAddBlockHook(3Xt)    XT FUNCTIONS     XtAppAddBlockHook(3Xt)

NAME

     XtAppAddBlockHook, XtRemoveBlockHook - register a block hook
     procedure

SYNTAX

     XtBlockHookId XtAppAddBlockHook(XtAppContext app_context,
          XtBlockHookProc proc, XtPointer client_data);

     void XtRemoveBlockHook(XtBlockHookId id);

ARGUMENTS

     app_context
               Specifies the application context.

     proc      Specifies the block hook procedure.

     num_args  Specifies the application-specific data to be
               passed to the block hook.

DESCRIPTION

     XtAppAddBlockHook registers the specified procedure and
     returns an identifier for it. The hook is called at any time
     in the future when the Intrinsics are about to block pending
     some input.

     Block hook procedures are removed automatically and the
     XtBlockHookId is destroyed when the application context in
     which they were added is destroyed.

     XtRemoveBlockHook removes the specified block hook procedure
     from the list in which it was registered.
