freerbuf(9F) Kernel Functions for Drivers freerbuf(9F)NAME
freerbuf - free a raw buffer header
SYNOPSIS
#include <sys/buf.h>
#include <sys/ddi.h>
void freerbuf(struct buf *bp);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
bp Pointer to a previously allocated buffer header structure.
DESCRIPTION
The freerbuf() function frees a raw buffer header previously allocated by getrbuf(9F). This function does not sleep and so may be called
from an interrupt routine.
CONTEXT
The freerbuf() function can be called from user, interrupt, or kernel context.

bioreset - reuse a private buffer header after I/O is complete
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 initialized by bioinit(9F).
CONTEXT
bioreset() can be called from any context.
SEE ALSO strategy(9E), bioinit(9F), biofini(9F), freerbuf(9F), getrbuf(9F), kmem_alloc(9F), kmem_free(9F), buf(9S)NOTES
bp must not describe a transfer in progress.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
