| | biofini - uninitialize a buffer structure |
SYNOPSIS
| |
#include <sys/ddi.h>
#include <sys/sunddi.h>
voidbiofini(struct buf *bp); |
| |
Solaris DDI specific (Solaris DDI).
|
| |
-
bp
- Pointer to the buffer header structure.
|
| |
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.
|
| |
The biofini() function can be called from any context.
|
| | Example 1. Using biofini
| |
| |
struct buf *bp = kmem_alloc(biosize(), KM_SLEEP);
bioinit(bp);
/* use buffer */
biofini(bp);
kmem_free(bp, biosize());
