bioinit(9F) Kernel Functions for Drivers bioinit(9F)
NAME
bioinit - initialize a buffer structure
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
voidbioinit(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 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.
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 */
