- register a block hook procedure
XtBlockHookId XtAppAddBlockHook(app_context,

- 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.
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.
