NAME
       insq - STREAMS: Inserts a STREAMS message into a queue

SYNOPSIS
       #include <sys/stream.h>

       int insq(
	       queue_t *message_queue,
	       MBLKP message,
	       MBLKP message_to_be_inserted );

ARGUMENTS
       Specifies a pointer to the message queue that contains the message passed to the message argument. The typedef queue_t is an alternate name
       for struct queue_entry *.  Specifies the enqueued message before which the new message is to be inserted. The typedef MBLKP is an alternate
       name for typedef struct msgb *.	Specifies the message to be inserted. The typedef MBLKP is an alternate name for typedef struct msgb *.

DESCRIPTION
       The  insq  interface  inserts a STREAMS message into a queue. The message to be inserted (the message_to_be_inserted argument) is placed in
       the queue (the message_queue argument) immediately before the message associated with the message argument.  If	the  message  argument	is
       NULL,  insq  places  the  new  message at the end of the queue. The interface ignores the queue class of the new message and it updates all
       flow-control parameters. The insq interface also enables the service procedure unless the QNOENB flag bit is set.

CAUTIONS
       If the message argument is non-NULL, it must point to a message on the queue or a system panic could occur.

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