NAME
       XtAppAddBlockHook, XtRemoveBlockHook - register a block hook procedure

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

       void XtRemoveBlockHook(idFP)
	       XtBlockHookId id;

ARGUMENTS
       Specifies  the application context.  Specifies the block hook procedure.  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.
