biofini(9F) Kernel Functions for Drivers biofini(9F) 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()); SEE ALSO
