linkb(9F)

NAME

linkb - concatenate two message blocks

#include <sys/stream.h> void linkb(mblk_t *mp1, mblk_t *mp2);

Architecture independent level 1 (DDI/DKI).

mp1: The message to which mp2 is to be added. mblk_t is an instance of the msgb(9S) structure.
mp2: The message to be added.

linkb() creates a new message by adding mp2 to the tail of mp1. The continuation pointer, b_cont, of mp1 is set to point to mp2.

linkb(mp1, mp2);

linkb() can be called from user or interrupt context.

See dupb(9F) for an example of using linkb().
