flushq(9r)


NAME

  flushq - STREAMS: Removes a message from a queue


SYNOPSIS

  #include <sys/stream.h>

  void flushq(
	  queue_t *queue,
	  int flag );


ARGUMENTS

  queue
      Specifies a pointer to the queue to be flushed. The typedef queue_t is
      an alternate name for struct queue_entry *.

  flag
      Specifies one of the following flag flush values:

      FLUSHDATA
	      Flush only data messages.	 These data messages are represented
	      by the M_DATA, M_DELAY, M_PROTO, and M_PCPROTO constants.

      FLUSHALL
	      Flush all messages. Requests a realtime delay


DESCRIPTION

  The flushq interface frees messages and their associated data structures by
  calling the freemsg interface. If the queue's count falls below the low-
  water mark and the QWANTW bit is set, flushq enables the nearest upstream
  service procedure.


RETURN VALUES

  None
