NAME

linkblk - STREAMS data structure sent to multiplexor drivers to indicate a link
 

SYNOPSIS

#include <sys/stream.h> 

INTERFACE LEVEL

Architecture independent level 1 (DDI/DKI)  

DESCRIPTION

The linkblk structure is used to connect a lower Stream to an upper STREAMS multiplexor driver. This structure is used in conjunction with the I_LINK, I_UNLINK, P_LINK, and P_UNLINK ioctl commands. See streamio(7I). The M_DATA portion of the M_IOCTL message contains the linkblk structure. Note that the linkblk structure is allocated and initialized by the Stream head as a result of one of the above ioctl commands.  

STRUCTURE MEMBERS

queue_t   *l_qtop;   /* lowest level write queue of upper stream */
                    /* (set to NULL for persistent links) */
queue_t   *l_qbot;   /* highest level write queue of lower stream */
int       l_index;   /* index for lower stream. */
