Your program actually says: 1) open file handle 2) create a String that will be read _on demand_ from file handle 3) close file handle 4) print the value which is computed from the String

Thanks for a clear explanation and that's also where I've got lost. Claus' explanation was helpfull too. I thought that the order things were done is 1) print the value which is computed from rechf to do so, 2) open file handle 3) create a String .... 4) close file handle hence my confusion. I think I kinda understand now what's going on, but the docs are definitely lacking here :( by the way, what would be a safe version of hGetContents ? and why hGetContents is unsafe ?
