Thanks Andrea Bergia.

I am using your code like this:

int dummy;
if (sscanf(string, "hello %d", &dummy))
    /* matched */

int dummy;
int n = sscanf(string, "hello %d", &dummy);
if (n == 1) {
    // Matched
}

Several ways to go about it. First thought is to use a regular expression, but that may be over kill for your requirements.
