DESCRIPTION

25       The  enableok() function enables queue q to be rescheduled for service.
26       It reverses the effect of a previous call to noenable(9F) on q by turn‐
27       ing off the QNOENB flag in the queue.
28

CONTEXT

30       The  enableok()  function can be called from user, interrupt, or kernel
31       context.
32

EXAMPLES

34       Example 1 Using emableok()
35
36
37       The qrestart() routine uses two STREAMS functions to  restart  a  queue
38       that  has  been disabled. The enableok() function turns off the  QNOENB
39       flag, allowing the qenable(9F) to schedule the queue for immediate pro‐
40       cessing.

47         5     enableok(rdwr_q);
48         6     /* re-enable a queue that has been disabled */
