ELOOP
Too many levels of symbolic links or prefixes.

ENAMETOOLONG
The length of the path string exceeds PATH_MAX, or a pathname component is longer than NAME_MAX.
ENOENT
This error code can mean the following:
  • A component of either path prefix doesn't exist.
  • The path points to an empty string.
ENOSPC
The directory that would contain the link can't be extended.
