NAME

bioinit - 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).

ARGUMENTS

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

struct buf * bp= kmem_alloc(biosize(), KM_SLEEP);

bioinit(bp);
/* use buffer * /
