#include <sys/stream.h> #include <sys/strsun.h> void miocack(queue_t *wq, mblk_t *mp, intcount, int rval);
To convert the message, miocack() 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. If the caller specifies a non-zero value for count, it is expected that the caller has already set 'mp->b_cont' field to point to a message block with a length of at least count bytes.
Callers that only need to perform the message conversion, or need to perform additional steps between the conversion and the sending of the M_IOCACK should use mioc2ack(9F).
