QUNTIMEOUT(9F)QUNTIMEOUT(9F)NAMEquntimeout - cancel previous qtimeout function call
SYNOPSIS
#include <sys/stream.h>
#include <sys/ddi.h>
clock_t quntimeout(queue_t *q, timeout_id_t id);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
q
Pointer to a STREAMS queue structure.
id
Opaque timeout ID a previous qtimeout(9F) call.
DESCRIPTION
The quntimeout() function 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 can‐
celled 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 mod‐
ule close returns. All outstanding timeouts and bufcalls must be can‐
celled before a driver close routine can block and before the close
routine calls qprocsoff(9F).
RETURN VALUES
The quntimeout() function returns -1 if the id is not found. Other‐
wise, quntimeout() returns a 0 or positive value.
CONTEXT
The quntimeout() function can be called from user, interrupt, or kernel
context.
