readlink error: Invalid argument about luaposix HOT 3 CLOSED

Thanks for your bug report. I don't see anything wrong here: if I run posix.readlink on a symlink, it returns the link; otherwise, it returns an error. Hence, I am guessing that in this case /tmp is not a symlink. Have you read readlink(2)?

Sorry. I think "readlink(path)" should return the absolute path.

posix.readlink should do what the POSIX function readlink does. As far as I can tell, it does this. As the man page says: "readlink() places the contents of the symbolic link path in the buffer buf". The only difference is that posix.readlink returns a string, as you don't have to worry about buffers in Lua. If the link is relative, then a relative path will be returned. If you want an absolute path, then at the moment you're out of luck, as you need "realpath", which is not currrently in luaposix. I'd be happy to accept a patch to add it.
