NAME
pmem2_config_set_required_store_granularity () - set a granularity in pmem2_config structure.
SYNOPSIS
#include <libpmem2.h>
enum pmem2_granularity {
PMEM2_GRANULARITY_BYTE,
PMEM2_GRANULARITY_CACHE_LINE,
PMEM2_GRANULARITY_PAGE,
};
int pmem2_config_set_required_store_granularity(struct pmem2_config *cfg,
enum pmem2_granularity g);
DESCRIPTION
The pmem2_config_set_required_store_granularity () sets a maximum permitted granularity g requested by user in the pmem2_config structure.
Granularity must be one of the following values:
|
• |
PMEM2_GRANULARITY_BYTE |
|||
|
• |
PMEM2_GRANULARITY_CACHE_LINE |
|||
|
• |
PMEM2_GRANULARITY_PAGE |
A description of the granularity concept can be found in libpmem2 (7) manpage.
RETURN VALUE
The pmem2_config_set_required_store_granularity () function returns 0 on success or a negative error code on failure.
ERRORS
The pmem2_config_set_required_store_granularity () can fail with the following errors:
|
• |
PMEM2_E_GRANULARITY_NOT_SUPPORTED - granularity g is not a valid value. |
