bbrreelleeaassee() -- Block-Device Routine

#iinncclluuddee <ssyyss/bbuuff.hh>

bbrreelleeaassee(_b_p)
BBUUFF *_b_p;

bbrreelleeaassee() unlocks and releases the buffer pointed to by _b_p.

A device  driver should always call   bbrreelleeaassee() when it no  longer needs a
buffer obtained  via a  bbrreeaadd().  If  a driver needs  to read and  modify a
block,  the recommended  sequence is  for  it to  call bbrreeaadd(),  modify the
block, set the BFMOD bit in the field bb_ffllaagg field, then call bbrreelleeaassee().
