clrbuf - erase the contents of a buffer
void clrbuf(struct buf *bp);
Architecture independent level 1 (DDI/DKI).
Pointer to the buf(9S) structure.
The clrbuf() function zeros a buffer and sets the b_resid member of the
buf(9S) structure to 0. Zeros are placed in the buffer starting at
bp→b_un.b_addr for a length of bp→b_bcount bytes. b_un.b_addr and
b_bcount are members of the buf(9S) data structure.
The clrbuf() function can be called from user, interrupt, or kernel
