Functions
faccessat(dirfd, path, access, flags)
—Tests permissions for a file or
directory.
fchmodat(dirfd, path, mode, 0)
—Sets file or directory permissions.
copyfile_state_alloc()
copyfile_state_free(state)
copyfile_state_get(state, flags, dst)
copyfile_state_get(state, COPYFILE_STATE_COPIED)
AT_FDCWD
—Returns a handle representing the current working directory.
fallocate(fd, mode, offset, len)
—Adjusts file allocation.
fchmod(fd)
—Sets open file or directory permissions.
fclonefileat(src, dst_dir, dst, flags)
—Efficiently copies between files.
fcntl(fd, F_DUPFD_CLOEXEC)
—Creates a new OwnedFd
instance that has
O_CLOEXEC
set and that shares the same underlying [file description] as
fd
.
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_RDADVISE, radvisory { offset, len })
fcntl(fd, F_SETFD, flags)
—Sets a file descriptor’s flags.
fcntl(fd, F_SETFL, flags)
—Sets a file descriptor’s status.
fcopyfile(from, to, state, flags)
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_GETPATH)
fcntl(fd, F_GETFL) & O_ACCMODE
linkat(old_dirfd, old_path, new_dirfd, new_path, flags)
—Creates a hard
link.
mkdirat(fd, path, mode)
—Creates a directory.
openat(dirfd, path, oflags, mode)
—Opens a file.
readlinkat(fd, path)
—Reads the contents of a symlink.
renameat(old_dirfd, old_path, new_dirfd, new_path)
—Renames a file or
directory.
lseek(fd, offset, whence)
—Repositions a file descriptor within a file.
fstatat(dirfd, path, flags)
—Queries metadata for a file or directory.
symlinkat(old_dirfd, old_path, new_dirfd, new_path)
—Creates a symlink.
lseek(fd, 0, SEEK_CUR)
—Returns the current position within a file.
unlinkat(fd, path, flags)
