C++ (Cpp) _read_offset Examples

Example #1

File: sst.c Project: SeKwonLee/lsm-tree-re

uint64_t sst_getoff(struct sst *sst, struct slice *sk)
{
	int lsn;
	uint64_t off = 0UL;
	struct meta_node *meta_info;

	meta_info = meta_get(sst->meta, sk->data);
	if(!meta_info)
		return 0UL;

	memcpy(sst->name, meta_info->index_name, FILE_NAME_SIZE);

	/* If get one record from on-disk sst file,
	 * this file must not be operated by bg-merge thread
	 */

	lsn = meta_info->lsn;
	if (sst->mutexer.lsn == lsn) {
		pthread_mutex_lock(&sst->mutexer.mutex);
		off = _read_offset(sst, sk);
		pthread_mutex_unlock(&sst->mutexer.mutex);
	} else {
		off = _read_offset(sst, sk);
	}

	return off;
}

Example #2

File: silopit.c Project: Zabrane/silokatana
