putq(D3)							      putq(D3)

NAME
     putq - put a message on a queue

SYNOPSIS
     #include <sys/stream.h>
     #include <sys/ddi.h>
     int putq(queue_t *q, mblk_t *bp);

   Arguments
     q	       Pointer to the queue.

     bp	       Pointer to the message.

DESCRIPTION
     putq is used to put messages on a queue after the put(D2) routine has
     finished processing the message.  The message is placed after any other
     messages of the same priority, and flow control parameters are updated.
     The queue's service routine is scheduled if it has not been disabled by a
     previous call to noenable(D3), or if the message being enqueued has
     greater than normal priority (that is, it is not in band zero).

   Return Values
     putq returns 1 on success and 0 on failure.

USAGE
     putq can fail if there is not enough memory to allocate the accounting
     data structures used with messages whose priority bands are greater than
     zero.

   Level
     Base or Interrupt.

   Synchronization Constraints
     Does not sleep.

     Driver-defined basic locks, read/write locks, and sleep locks may be held
     across calls to this function.

   Examples
     See datamsg(D3) for an example of putq.
