NAME
       qband - STREAMS queue flow control information structure

SYNOPSIS
       #include <sys/stream.h>

INTERFACE LEVEL
       Architecture independent level 1 (DDI/DKI)

DESCRIPTION
       The  qband structure contains flow control information for each priority band in a queue.

       The qband structure is defined as type qband_t.

STRUCTURE MEMBERS
       struct	     qband*qb_next;	/* next band's info */
       size_t	     qb_count		/* number of bytes in band */
       struct msgb   *qb_first; 	/* start of band's data */
       struct msgb   *qb_last;		/* end of band's data */
       size_t	     qb_hiwat;		/* band's high water mark */
       size_t	     qb_lowat;		/* band's low water mark */
       uint_t	     qb_flag;		/* see below */

       Valid flags are as follows:

       QB_FULL	       Band is considered full.

       QB_WANTW        Someone wants to write to band.

NOTES
       All access to this structure should be through strqget(9F) and strqset(9F). It is logically part of the queue(9S) and its layout and parti-
       tioning with respect to that structure might change in future releases. If portability is a concern, do not declare or store  instances	of
       or references to this structure.
