Not sure about a function that comes with the C compiler, but I usually just
write my own:

int string2int(char *s)
    {
    int place = 1;
// the current place it is reading (i.e. 1's 10's 100's)
    int r = 0;
// the final product (or where it WILL be)
    for(n = strlen(s); n >=0; --n, place *= 10)                    // start
at the right and count to the left
        r += (*(s + n) - 48) * place;
// 48 is the ASCII value for '0', so to convert from a single char

// to it's integer value, you would simply subtract 48
    return r;
    }

There you have it

(in case you are wondering, all my indents are screwed up beacuse I'm trying
to type this in a, what's the word??, non-monospaced font.)

Hope this helps,
