To get it to work, the digit checking loop needs to be changed to:

					if (*s < '0' || *s > '9')
					{
						if (*s == '-') continue;

But if that's done the function will still return '-1' (a valid negative number) when a non-valid number (e.g. text) is passed to the function, therefor you can't do error checking if you want to support '-1' as a value.

I guess you could change the function to return true/false and make it take a variable as parameter to store the value in.
