msgb(9S)						    Data Structures for Drivers 						  msgb(9S)

NAME

       msgb, mblk - STREAMS message block structure

SYNOPSIS

       #include <sys/stream.h>

INTERFACE LEVEL

       Architecture independent level 1 (DDI/DKI)

DESCRIPTION

       A  STREAMS  message  is made up of one or more message blocks, referenced by a pointer to a msgb structure. The b_next and  b_prev pointers
       are used to link messages together on a QUEUE. The  b_cont pointer links message blocks together when a message consists of more  than  one
       block.

       Each   msgb  structure also includes a pointer to a  datab(9S) structure, the data block (which contains pointers to the actual data of the
       message), and the type of the message.

STRUCTURE MEMBERS

	 struct msgb	 *b_next;    /* next message on queue */
	 struct msgb	 *b_prev;    /* previous message on queue */
	 struct msgb	 *b_cont;    /* next message block */
	 unsigned char	 *b_rptr;    /* 1st unread data byte of buffer */
	 unsigned char	 *b_wptr;    /* 1st unwritten data byte of buffer */
	 struct datab	 *b_datap;   /* pointer to data block */
	 unsigned char	 b_band;     /* message priority  */
	 unsigned short  b_flag;     /* used by stream head  */

       Valid flags are as follows:

       MSGMARK	    Last byte of message is marked.

       MSGDELIM     Message is delimited.

       The msgb structure is defined as type mblk_t.
