| Kernel Functions for Drivers | bioinit(9F) |
| | bioinit - initialize a buffer structure |
SYNOPSIS
| |
#include <sys/ddi.h>
#include <sys/sunddi.h>
voidbioinit(struct buf *bp); |
| |
Solaris DDI specific (Solaris DDI).
|
| |
-
bp
- Pointer to the buffer header structure.
|
| |
The bioinit() function initializes a buf(9S)
structure. A buffer structure contains state information which has to be initialized if the memory for the buffer was allocated using kmem_alloc(9F). This is not necessary for a buffer allocated using getrbuf(9F) because getrbuf() will call bioinit() directly.
|
| |
The bioinit() function can be called from any context.
|
| | Example 1. Using bioinit
| |
| |
struct buf *bp = kmem_alloc(biosize(), KM_SLEEP);
bioinit(bp);
/* use buffer */
