        size_t length);

DESCRIPTION

The pmemset_config_set_length() function configures the length which will be used for mapping. *map_cfg should be already initialized, please see pmemset_map_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.
