bioinit - initialize a buffer structure SYNOPSIS
#include <sys/ddi.h> #include <sys/sunddi.h> voidbioinit(struct buf *bp); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
bp Pointer to the buffer header structure. DESCRIPTION
The 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. CONTEXT
The bioinit() function can be called from any context. EXAMPLES
Example 1: Using bioinit() struct buf *bp = kmem_alloc(biosize(), KM_SLEEP); bioinit(bp); /* use buffer */ SEE ALSO
