#include <sys/stream.h> #include <sys/strsun.h> void mioc2ack(mblk_t *mp, mblk_t *dp, size_t count, int rval);
To convert the message, mioc2ack() changes the message type to M_IOCACK, sets the ioc_count and ioc_rval members of the iocblk(9S) associated with mp to the passed-in values, and clears the ioc_error field. Further, it frees any message blocks chained off of mp->b_cont and resets mp->b_cont to dp. Finally, if dp is not NULL, mioc2ack() resets dp->b_wptr to be dp->b_rptr + count (that is, it sets dp to be exactly count bytes in length).
