Kernel & Driver Data Structures                                       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 mes‐
       sage), 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.
