NAME

pmem2_map_get_store_granularity() - reads effective mapping granularity

SYNOPSIS

    #include <libpmem2.h>
    enum pmem2_granularity {
        PMEM2_GRANULARITY_BYTE,
        PMEM2_GRANULARITY_CACHE_LINE,
        PMEM2_GRANULARITY_PAGE,
    };
    enum pmem2_granularity pmem2_map_get_store_granularity(struct pmem2_map *map);

DESCRIPTION

The pmem2_map_get_store_granularity() function reads granularity of the created mapping. The map parameter points to the structure describing mapping created using the pmem2_map_new(3) function. Concept of the granularity is described in libpmem2(7).
