NAME

SYNOPSIS

9       #include <sys/ddi.h>
10       #include <sys/sunddi.h>

INTERFACE LEVEL

PARAMETERS

19       bp    Pointer to the buffer header structure.

DESCRIPTION

23       The bioinit() function initializes a buf(9S) structure. A buffer struc‐
24       ture contains state information which has to be initialized if the mem‐
25       ory for the buffer was allocated using kmem_alloc(9F). This is not nec‐
26       essary for a buffer allocated using getrbuf(9F) because getrbuf()  will
27       call bioinit() directly.
28

CONTEXT

30       The bioinit() function can be called from any context.
31

EXAMPLES

33       Example 1 Using bioinit()

36         struct buf *bp = kmem_alloc(biosize(), KM_SLEEP);
37         bioinit(bp);
38         /* use buffer */
