Architecture independent level 1 (DDI/DKI).
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.
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:
The msgb structure is defined as type mblk_t.
