Functions
faccessat(dirfd, path, access, flags)—Tests permissions for a file or
directory.
fchmodat(dirfd, path, mode, 0)—Sets file or directory permissions.
fchownat(dirfd, path, owner, group, flags)—Sets file or directory
ownership.
copy_file_range(fd_in, off_in, fd_out, off_out, len, 0)—Copies data
from one file to another.
AT_FDCWD—Returns a handle representing the current working directory.
posix_fadvise(fd, offset, len, advice)—Declares an expected access
pattern for a file.
fallocate(fd, mode, offset, len)—Adjusts file allocation.
fchmod(fd)—Sets open file or directory permissions.
fchown(fd)—Sets open file or directory ownership.
fcntl(fd, F_DUPFD_CLOEXEC)—Creates a new OwnedFd instance, with value
at least min, that has O_CLOEXEC set and that shares the same
underlying [file description] as fd.
fcntl(fd, F_GET_SEALS)
fcntl(fd, F_GETFD)—Returns a file descriptor’s flags.
fcntl(fd, F_GETFL)—Returns a file descriptor’s access mode and status.
fcntl(fd, F_SETFD, flags)—Sets a file descriptor’s flags.
fcntl(fd, F_SETFL, flags)—Sets a file descriptor’s status.
fdatasync(fd)—Ensures that file data is written to the underlying
storage device.
flock(fd, operation)—Acquire or release an advisory lock on an open file.
fstat(fd)—Queries metadata for an open file or directory.
fstatfs(fd)—Queries filesystem statistics for an open file or directory.
fsync(fd)—Ensures that file data and metadata is written to the
underlying storage device.
ftruncate(fd, length)—Sets the length of a file.
futimens(fd, times)—Sets timestamps for an open file or directory.
fcntl(fd, F_GETFL) & O_ACCMODE
linkat(old_dirfd, old_path, new_dirfd, new_path, flags)—Creates a hard
link.

readlinkat(fd, path)—Reads the contents of a symlink.
renameat(old_dirfd, old_path, new_dirfd, new_path)—Renames a file or
directory.
renameat2(old_dirfd, old_path, new_dirfd, new_path, flags)—Renames a
file or directory.
lseek(fd, offset, whence)—Repositions a file descriptor within a file.
