.SH NAME
hugetlbfs_find_path, hugetlbfs_find_path_for_size - Locate an appropriate hugetlbfs mount point
.SH SYNOPSIS
.B #include <hugetlbfs.h>

.br
const char *hugetlbfs_find_path(void);
.br
const char *hugetlbfs_find_path_for_size(long page_size);

.SH DESCRIPTION

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)).

.SH RETURN VALUE

On success, a non-NULL value is returned.
On failure, NULL is returned.
