NAME
pmem2_config_set_sharing () - set sharing in the pmem2_config structure
SYNOPSIS
#include <libpmem2.h>
struct pmem2_config;
enum pmem2_sharing_type {
PMEM2_SHARED,
PMEM2_PRIVATE,
};
int pmem2_config_set_sharing(struct pmem2_config *config, enum pmem2_sharing_type sharing);
DESCRIPTION
The pmem2_config_set_sharing () function configures the behavior and visibility of writes to the mapping’s pages. The possible values are listed below:
|
• |
PMEM2_SHARED - Writes are made directly to the underlying memory, making them visible to other mappings of the same memory region. (default) |
||
|
• |
PMEM2_PRIVATE - Writes do not affect the underlying memory and are not visible to other mappings of the same memory region. |
RETURN VALUE
The pmem2_config_set_sharing () function returns 0 on success or a negative error code on failure.
ERRORRS
The pmem2_config_set_sharing () can fail with the following errors:
|
• |
PMEM2_E_INVALID_SHARING_VALUE - sharing value is invalid. |
