NAME

XtAppAddBlockHook, XtRemoveBlockHook - register a block hook procedure

SYNTAX

#include <X11/Intrinsic.h>

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.

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.
