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.
