SYNOPSIS

#include <sys/stream.h>
#include <sys/ddi.h>
clock_t quntimeout(queue_t *q, timeout_id_t id); |
| |
Solaris DDI specific (Solaris DDI).

-
id
- Opaque timeout ID a previous qtimeout(9F) call.

quntimeout() cancels a pending qtimeout(9F) request. The quntimeout() function is tailored to be used with the enhanced STREAMS framework interface, which is based on the concept of perimeters. (See mt-streams(9F).) quntimeout() returns when the timeout has been cancelled or finished executing. The timeout
will be cancelled even if it is blocked at the perimeters associated with the queue. quntimeout() should be executed for all outstanding timeouts before a driver or module close returns.
|
| |
quntimeout() returns -1 if the id is not found. Otherwise, quntimeout() returns a 0
or positive value.
|
| |
quntimeout() can be called from user or interrupt context.
