NAME
     clrbuf - erase the contents of a buffer

SYNOPSIS
     #include 
     #include 



     void clrbuf(struct buf *bp);


INTERFACE LEVEL
     Architecture independent level 1 (DI/DKI).

PARAMETERS
     bp    Pointer to the buf(9S) structure.


DESCRIPTION
     The clrbuf() function zeros a buffer and  sets  the  bresid
     member  of  the  buf(9S) structure to 0. Zeros are placed in
     the buffer starting  at  bp->bun.baddr  for  a  length  of
     bp->bbcount  bytes. bun.baddr and bbcount are members of
     the buf(9S) data structure.

CONTEXT
     The clrbuf() function can be called from user, interrupt, or
     kernel context.
