A buffer structure contains state information which has to be initialized if the memory for the buffer was allocated using \fBkmem_alloc\fR(9F). This is not necessary for a buffer allocated using \fBgetrbuf\fR(9F) because \fBgetrbuf()\fR will call \fBbioinit()\fR directly. .SH CONTEXT .sp .LP The \fBbioinit()\fR function can be called from any context. .SH EXAMPLES .LP \fBExample 1 \fRUsing \fBbioinit()\fR .sp .in +2 .nf struct buf *bp = kmem_alloc(biosize(), KM_SLEEP); bioinit(bp); /* use buffer */ .fi .in -2 .SH SEE ALSO .sp .LP \fBbiofini\fR(9F), \fBbioreset\fR(9F), \fBbiosize\fR(9F), \fBgetrbuf\fR(9F), \fBkmem_alloc\fR(9F), \fBbuf\fR(9S) .sp .LP \fIWriting Device Drivers\fR
