NAME
pmem2_config_set_length () - set length in the pmem2_config structure
SYNOPSIS
#include <libpmem2.h> struct pmem2_config; int pmem2_config_set_length(struct pmem2_config *config, size_t length);
DESCRIPTION
The pmem2_config_set_length () function configures the length which will be used for mapping. *config should be already initialized, please see pmem2_config_new (3) for details. The must be a multiple of the alignment required for the data source which will be used for mapping alongside the config. To retrieve the alignment required for specific instance of pmem2_source** use pmem2_source_alignment (3). By default, the length is equal to the size of the file that is being mapped.
RETURN VALUE
The pmem2_config_set_length () function always returns 0.
