NAME
bioreset - reuse a private buffer header after I/O is complete
SYNOPSIS
#include <sys/buf.h>
#include <sys/ddi.h>
void bioreset(
struct buf *bp);
INTERFACE LEVEL
illumos DDI specific (illumos DDI)
PARAMETERS
bp Pointer to the
buf(9S) structure.
DESCRIPTION
bioreset() is used by drivers that allocate private buffers with
getrbuf(9F) or
kmem_alloc(9F) and want to reuse them in multiple
transfers before freeing them with
freerbuf(9F) or
kmem_free(9F).
bioreset() resets the buffer header to the state it had when
initially allocated by
getrbuf() or initialized by
bioinit(9F).
CONTEXT
bioreset() can be called from any context.
