C Issue WAIT FOR DIGIT

Hi,
Was playing around with AGI in C and couldn’t seem to get this to work, was wondering if anyone had any ideas?
It answers but no matter what digit I hit it will wait the full 10 seconds before timing out and returning:
200 result=0

> #include <stdio.h>
> #include <string.h>

>       FILE *f;

>       setlinebuf(stdout);
>       setlinebuf(stderr);

>       f = fopen("test.log", "a");

>       if (!f) {
>         return 0;

>       fprintf(stdout, "WAIT FOR DIGIT 10000\n");

>       fgets(line,80,stdin);

>       fclose(f);

>       return 1;

This ended up working. It was a port blocking problem.
