NAME
XtAppAddBlockHook, XtRemoveBlockHook - register a block hook procedure
SYNTAX

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

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.
