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 */
