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 ∗/
