hugetlbfs_find_path, hugetlbfs_find_path_for_size — Locate an appropriate hugetlbfs mount point
const char *hugetlbfs_find_path(void);
const char *hugetlbfs_find_path_for_size(long page_size);
These functions return a pathname for a mounted hugetlbfs filesystem for the appropriate huge page size. For hugetlbfs_find_path, the default huge page size is used (see gethugepagesize(3)). For hugetlbfs_find_path_for_size, a valid huge page size must be specified (see gethugepagesizes(3)).
On success, a non-NULL value is returned. On failure, NULL is returned.
