NAME

biofini - uninitialize a buffer structure

SYNOPSIS

#include <sys/ddi.h>
#include <sys/sunddi.h>
void biofini(struct buf *bp);

INTERFACE LEVEL

illumos DDI specific (illumos DDI).

PARAMETERS

Pointer to the buffer header structure.

DESCRIPTION

The biofini() function uninitializes a buf(9S) structure. If a buffer structure has been allocated and initialized using kmem_alloc(9F) and bioinit(9F) it needs to be uninitialized using biofini() before calling kmem_free(9F). It is not necessary to call biofini() before freeing a buffer structure using freerbuf(9F) because freerbuf() will call biofini() directly.

CONTEXT

The biofini() function can be called from any context.

EXAMPLES

Example 1 Using biofini()

struct buf *bp = kmem_alloc(biosize(), KM_SLEEP);
bioinit(bp);
/* use buffer */
biofini(bp);
kmem_free(bp, biosize());
