BIOINIT(9F)BIOINIT(9F)NAMEbioinit - initialize a buffer structure
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
void bioinit(struct buf *bp);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
bp
Pointer to the buffer header structure.
DESCRIPTION
The bioinit() function initializes a buf(9S) structure. A buffer struc‐
ture contains state information which has to be initialized if the mem‐
ory for the buffer was allocated using kmem_alloc(9F). This is not nec‐
essary for a buffer allocated using getrbuf(9F) because getrbuf() will
call bioinit() directly.
CONTEXT
The bioinit() function can be called from any context.
EXAMPLES
Example 1 Using bioinit()
struct buf *bp = kmem_alloc(biosize(), KM_SLEEP);
bioinit(bp);
/* use buffer */
