| | 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); |
| |
Solaris DDI specific (Solaris DDI)
|
| |
-
bp
- Pointer to the buf(9S) structure.
|
| |
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).
|
| |
bioreset() can be called from any context.
|
| |
bp must not describe a transfer in progress.
