BIORESET 9F "Nov 15, 1996"
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
Solaris DDI specific (Solaris 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.
SEE ALSO
strategy(9E), bioinit(9F), biofini(9F), freerbuf(9F), getrbuf(9F), kmem_alloc(9F), kmem_free(9F), buf(9S)
NOTES
bp must not describe a transfer in progress.
