hugetlbfs_unlinked_fd, hugetlbfs_unlinked_fd_for_size - Obtain a file descriptor
for a new unlinked file in hugetlbfs
#include <hugetlbfs.h>
int hugetlbfs_unlinked_fd(void);
int hugetlbfs_unlinked_fd_for_size(long page_size);
These functions return an open file descriptor for a unique, newly-created file
in a hugetlbfs filesystem. To avoid leaking hugepages, the file is unlinked
automatically before the function returns.
For hugetlbfs_unlinked_fd, the default huge page size is used (see
gethugepagesize(3)). For hugetlbfs_unlinked_fd_for_size, a valid huge page
size must be specified (see
gethugepagesizes(3)).
On success, a valid open file descriptor is returned. On failure, -1 is returned
and errno may be set appropriately.
