Re: hex to int

I have written this small program and I must admit I'm a little stuck.
Input should be a hex number like fff or 0xfff and convert it to the
decimal equivalent. The output I get is always 0.

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char **argv)
{
if (argc != 2) {
puts("hex usage error");
exit(EXIT_FAILURE);
}
int x = strtol(argv[1], NULL, 10);
printf("%i\n", x);
return 0;
}

Am I missing a std function here that could do this for me? I know error
checking is not present.

I see that strtol returns a long. Could this be part of the problem?
