If FD is AT_FDCWD, FILENAME is interpreted relative to the current working directory, as in openat. If the link is small enough to fit into BUFFER put it there. BUFFER's size is BUFFER_SIZE, and BUFFER can be null if BUFFER_SIZE is zero. If the link is not small, put it into a dynamically allocated buffer managed by ALLOC. It is the caller's responsibility to free the returned value if it is nonnull and is not BUFFER. The PREADLINKAT function specifies how to read links. It operates like POSIX readlinkat() <http://pubs.opengroup.org/onlinepubs/9699919799/functions/readlink.html> but can assume that its first argument is the same as FD.
