print(buf)
The trick here is to replace the above line with:
print(String(validatingUTF8: buf))
`fgets` sets up `buf` to hold a C string, so you have to convert it to
a Swift string. How do you do this depends on the encoding of the
bytes. If you expect the C string to be UTF-8, then
`String(validatingUTF8:)` is the way to go.
IMPORTANT: This conversion can fail, which is why the above will print
a bunch of optional strings, and you will have to decide what to your
program should do when it does.

btw This question came up recently. See the thread for other
suggestions about how to handle it.

Hi Quinn,
The link you referenced above
<http://article.gmane.org/gmane.comp.lang.swift.user/1943> is all about
Swift 2.2. I had already found that one on StackOverflow and gave it a
try, which caused me to generate the string of queries, when it all fell
apart under Swift 3.
