putq(9r)


NAME

  putq - STREAMS: Puts a message on a queue


SYNOPSIS

  #include <sys/stream.h>

  int putq(
	  queue_t *queue_pointer,
	  MBLKP message_ptr );


ARGUMENTS

  queue_pointer
      Specifies a pointer to the queue to which the message is to be added.
      The typedef queue_t is an alternate name for struct queue_entry *.

  message_ptr
      Specifies a pointer to the message block to be placed on the queue. The
      typedef MBLKP is an alternate name for typedef struct msgb *.


DESCRIPTION

  The putq interface puts a message on a driver's queue after the module's
  put interface has finished processing the message. The putq interface
  places the message after any other messages of the same priority and then
  updates any flow-control parameters. If the QNOENB flag bit is not set,
  putq enables the service interface. If no processing is done, the putq
  interface can be used as the module's put interface.


RETURN VALUES

  Upon successful completion, putq returns the value 1. On failure, it
  returns the value zero (0).
