Okay. Normally you want to use a library that someone else has
tested.  So:

sscanf("%x", &i);

If you don't have access to any libraries, then:

/*
 * Return the integer value of the hex string s. Allowable characters
 * are 0-9, a-f, A-F.  Any other character causes scanning to stop and
 * the hex value of the string up to that character is returned. If
the first
 * character is non-hex, then zero is returned.
 */
int hex_to_int(char *s)
{
  int i = 0;
  while (*s) {
    if ('0' <= *s && *s <= '9')
      i = (i << 4) + (*s - '0');
    else if ('a' <= *s && *s <= 'f')
      i = (i << 4) + *s + (10 - 'a');
    else if ('A' <= *s && *s <= 'F')
      i = (i << 4) + *s + (10 - 'A');
    else break;
    s++;
  }
  return i;
}
