Kernel Functions for Driversbioinit(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 */

SEE ALSO
