NAME

       biofini - uninitialize a buffer structure

SYNOPSIS

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

       voidbiofini(struct buf *bp);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

       bp	Pointer to the buffer header structure.

DESCRIPTION

       The biofini() function uninitializes a buf(9S) structure. If a buffer structure has been allocated and initialized using kmem_alloc(9F) and
       bioinit(9F) it needs to be uninitialized using biofini() before calling kmem_free(9F). It is not necessary to call biofini() before freeing
       a buffer structure using freerbuf(9F) because freerbuf() will call biofini() directly.

CONTEXT

       The biofini() function can be called from any context.

EXAMPLES

       Example 1: Using biofini()

       struct buf *bp = kmem_alloc(biosize(), KM_SLEEP);
       bioinit(bp);
       /* use buffer */
       biofini(bp);
       kmem_free(bp, biosize());
