bioreset(9F)

NAME

     bioreset - reuse a private buffer header after I/O  is  com-
     plete

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  ini-
     tialized by bioinit(9F).

CONTEXT

     bioreset() can be called from any context.

NOTES

     bp must not describe a transfer in progress.
