Regular expressions

You can't.
There is only one thing which even comes close, and that is a scan set (or it's complement).
Eg.
[tt]scanf( "%[0-9]", myNumStr );[/tt]
Which in regex terms is [tt][0-9]+[/tt]
If you want anything more complicated than that, then the best thing to do is read a line using fgets(), then use one of the standard regex packages and parse the line yourself.

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
