void bioreset(struct buf ∗bp);

INTERFACE LEVEL

ARGUMENTS

bp Pointer to the buf(9S) structure. 

DESCRIPTION

bioreset() is used by drivers that allocate private buffers with getrbuf(9F) and want to reuse them in multiple transfers before freeing them with freerbuf(9F).  bioreset() resets the buffer header to the state it had when initially allocated. 

CONTEXT

bioreset() can be called from any context. 

SEE ALSO

strategy(9E), freerbuf(9F), getrbuf(9F), buf(9S)

NOTES
