Specifically: .sp .LP DB_BASE(mp) is equivalent to \fBmp->b_datap->db_base\fR. .sp .LP DB_LIM(mp) is equivalent to \fBmp->b_datap->db_lim\fR. .sp .LP DB_TYPE(mp) is equivalent to \fBmp->b_datap->db_type\fR. .sp .LP DB_REF(mp) is equivalent to \fBmp->b_datap->db_ref\fR. .SH CONTEXT .sp .LP These functions can be called from user, kernel or interrupt context. .SH SEE ALSO .sp .LP \fBdatab\fR(9S), \fBmsgb\fR(9S) .sp .LP \fISTREAMS Programming Guide\fR
