bioreset(9F)						   Kernel Functions for Drivers 					      bioreset(9F)

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.
