freerbuf(9f) [xfree86 man page]

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

       freerbuf() frees a raw buffer header previously allocated by getrbuf(9F).  This function does not sleep and so may be called from an inter-
       rupt routine.

CONTEXT

       freerbuf() can be called from user or interrupt context.

SEE ALSO

       getrbuf(9F), kmem_alloc(9F), kmem_free(9F), kmem_zalloc(9F)

bioreset(9F)						   Kernel Functions for Drivers 					      bioreset(9F)

NAME

       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.
