#include <sys/stream.h> #include <sys/strsun.h> void miocnak(queue_t *wq, mblk_t *mp, int count, int error);
To convert the message, miocnak() changes the message type to M_IOCNAK, sets the ioc_count and ioc_error members of the iocblk(9S) associated with mp to the passed-in values, and clears the ioc_rval field. Since payloads cannot currently be associated with M_IOCNAK messages, count must always be zero. If error is passed as zero, EINVAL is assumed.
