Kernel Functions for Drivers                         enableok(9F)



NAME
     enableok - reschedule a queue for service

SYNOPSIS
     #include 
     #include 



     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  }
