HUGETLBFS_UNLINKED_FD(3)				     Library Functions Manual					  HUGETLBFS_UNLINKED_FD(3)

NAME

       hugetlbfs_unlinked_fd, hugetlbfs_unlinked_fd_for_size - Obtain a file descriptor for a new unlinked file in hugetlbfs

SYNOPSIS

       #include <hugetlbfs.h>

       int hugetlbfs_unlinked_fd(void);
       int hugetlbfs_unlinked_fd_for_size(long page_size);

DESCRIPTION

       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)).

RETURN VALUE

       On success, a valid open file descriptor is returned.  On failure, -1 is returned and errno may be set appropriately.

HUGETLBFS_FIND_PATH(3)					     Library Functions Manual					    HUGETLBFS_FIND_PATH(3)

NAME

       hugetlbfs_find_path, hugetlbfs_find_path_for_size - Locate an appropriate hugetlbfs mount point

SYNOPSIS

       #include <hugetlbfs.h>

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

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)).

RETURN VALUE

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