biofini - uninitialize a buffer structure
#include <sys/ddi.h> #include <sys/sunddi.h> voidbiofini(struct buf *bp);
Solaris DDI specific (Solaris DDI).
bp
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.
The biofini() function can be called from any context.
Example 1 Using biofini()
struct buf *bp = kmem_alloc(biosize(), KM_SLEEP); bioinit(bp); /* use buffer */ biofini(bp); kmem_free(bp, biosize());
bioinit(9F), bioreset(9F), biosize(9F), freerbuf(9F), kmem_alloc(9F), kmem_free(9F), buf(9S)
