NAME
qb_rb_chunk_alloc - Allocate space for a chunk of the given size.
SYNOPSIS
#include <qb/qbrb.h>
void *
qb_rb_chunk_alloc
(
qb_ringbuffer_t *
rb
, /* ringbuffer instance */
size_t
len
/* (in) the size to allocate. */
);
PARAMS
rb ringbuffer instance
len (in) the size to allocate.
DESCRIPTION
If type == QB_RB_FLAG_OVERWRITE and NULL is returned, memory corruption of the memory file has occurred. The ringbuffer should be destroyed. If type == QB_RB_NORMAL then when there is not enough space it will return NULL.
RETURN VALUE
pointer to chunk to write to, or NULL (if no space).
