enableok - reschedule a queue for service
#include <sys/stream.h> #include <sys/ddi.h> void enableok(queue_t *q);
Architecture independent level 1 (DDI/DKI).
A pointer to the queue to be rescheduled.
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.
The enableok() function can be called from user, interrupt, or kernel 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.
