#include <sys/buf.h>
#include <sys/ddi.h>
void bioreset(struct buf *bp);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
PARAMETERS
bp Pointer to the buf(9S) structure.
DESCRIPTION
bioreset() is used by drivers that allocate private buffers with getr‐
buf(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.
SEE ALSO

kmem_alloc(9F), kmem_free(9F), buf(9S)
NOTES
bp must not describe a transfer in progress.
