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 turn‐
       ing 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 pro‐
       cessing.

	 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  }
