NAME
       putctl - STREAMS: Puts a control message on a queue

SYNOPSIS
       #include <sys/stream.h>

       int putctl(
	       queue_t *queue_pointer,
	       int type );

ARGUMENTS
       Specifies  a  pointer  to  the queue to which the message is to be sent. The typedef queue_t is an alternate name for struct queue_entry *.
       Specifies a message type (must be control and not a data type).

DESCRIPTION
       The putctl interface tests the type argument to make sure a data type was not specified. It then attempts to allocate a message block.  The
       putctl interface fails if a message block cannot be allocated or if the type argument is M_DELAY, M_PROTO, or M_PCPROTO.

NOTES
       The putctl interface calls the putctl_comm interface, which actually performs the work of sending the control message.

RETURN VALUES
       Upon  successful  completion,  putctl returns the value 1. The putctl interface fails if a message block cannot be allocated or if the type
       argument is M_DELAY, M_PROTO, or M_PCPROTO.
