.SH DESCRIPTION
.sp
.LP
\fBbioreset()\fR is used by drivers that allocate private buffers with \fBgetrbuf\fR(9F) or \fBkmem_alloc\fR(9F) and want to reuse them in multiple transfers before freeing them with \fBfreerbuf\fR(9F) or \fBkmem_free\fR(9F). \fBbioreset()\fR resets the buffer header to the state it had when initially allocated by \fBgetrbuf()\fR or initialized by \fBbioinit\fR(9F). 
.SH CONTEXT
.sp
.LP
\fBbioreset()\fR can be called from any context.
