putq(9F)

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 pro-
     cessing is done, putq() can be used as the module's put rou-
     tine.

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().
