bioinit(9F) Kernel Functions for Drivers bioinit(9F)NAMEbioinit - initialize a buffer structureSYNOPSIS#include <sys/ddi.h> #include <sys/sunddi.h> voidbioinit(struct buf *bp);INTERFACE LEVELSolaris DDI specific (Solaris DDI).PARAMETERSbp Pointer to the buffer header structure.DESCRIPTIONThe 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.CONTEXTThe bioinit() function can be called from any context.EXAMPLESExample 1 Using bioinit() struct buf *bp = kmem_alloc(biosize(), KM_SLEEP); bioinit(bp); /* use buffer */SEE ALSObiofini(9F), bioreset(9F), biosize(9F), getrbuf(9F), kmem_alloc(9F), buf(9S) Writing Device Drivers SunOS 5.11 20 Nov 1996 bioinit(9F)
