If you want to place \d in C string literal, write \\ twise. Didn't you know that backslash is a special escape character in C?

There is exactly this example, just reading from stdin instead of custom file, at http://mij.oltrelinux.com/devel/unixprg/#regex . There's also a quick reference on the RegEx syntax on there.
