#include <libpmem2.h>

struct pmem2_config;
int pmem2_config_set_offset(struct pmem2_config *config, size_t offset);

DESCRIPTION

The pmem2_config_set_offset() function configures the offset which will be used to map the contents from the specified location of the source. *config should be already initialized, please see pmem2_config_new(3) for details. The \offset must be a multiple of the alignment required for the config. The alignment requirements are specific to a data source. To retrieve the alignment required for specific instance of pmem2_source* use pmem2_source_alignment(3).

• PMEM2_E_OFFSET_OUT_OF_RANGE - argument out of range, offset is greater than INT64_MAX
