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

       enableok()  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

       enableok() can be called from user or interrupt 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  }

NAME

       putq - put a message on a queue

SYNOPSIS

       #include <sys/stream.h>

       int putq(queue_t *q, mblk_t *bp);

INTERFACE LEVEL

       Architecture independent level 1 (DDI/DKI).

PARAMETERS

       q	Pointer to the queue to which the message is to be added.

       bp	Message to be put on the queue.

DESCRIPTION

       putq()  is  used  to  put  messages  on a driver's queue after the module's put routine has finished processing the message. The message is
       placed after any other messages of the same priority, and flow control parameters are updated. If QNOENB is not set, the service routine is
       enabled. If no other processing is done, putq() can be used as the module's put routine.

RETURN VALUES

       putq() returns 1 on success and 0 on failure.

       Note -  Upon failure, the caller should call freemsg(9F) to free the pointer to the message block.

CONTEXT

       putq() can be called from user or interrupt context.

EXAMPLES

       See the datamsg(9F) function page for an example of putq().
