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  }
