enableok(9F) Kernel Functions for Drivers enableok(9F)
NAME
enableok - reschedule a queue for service
SYNOPSIS
#include <sys/stream.h>
#include <sys/ddi.h>
void enableok(queue_t *q);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
q A pointer to the queue to be rescheduled.
DESCRIPTION
The enableok() function enables queue q to be rescheduled for service. It reverses the effect of a previous call to noenable(9F) on q by
turning off the QNOENB flag in the queue.
CONTEXT
The enableok() function can be called from user, interrupt, or kernel context.
EXAMPLES
Example 1 Using emableok()
The qrestart() routine uses two STREAMS functions to restart a queue that has been disabled. The enableok() function turns off the QNOENB
flag, allowing the qenable(9F) to schedule the queue for immediate processing.
1 void
2 qrestart(rdwr_q)
3 register queue_t *rdwr_q;
4 {
5 enableok(rdwr_q);
6 /* re-enable a queue that has been disabled */
7 (void) qenable(rdwr_q);
8 }
