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

enableok() 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

enableok() can be called from user or interrupt context.

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 }
