NAME
     putq - put a message on a queue

SYNOPSIS
     #include 



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


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

CONTEXT
     The putq() function can be called from user,  interrupt,  or
     kernel context.

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