Basic TAP test

eg.c

int main()
{
    const char *answer;
    plan_tests(2); 
    answer = read_answer(stdin);
    if (!answer){
        fail("Malformed JSON data provided");
    } else { 
        pass("Valid JSON data recieved");
    }

    skip_start(! answer, 1,  "Skipping because malformed JSON data received") ;
        ok(check_banned(answer), "No banned functions allowed");
    skip_end;
   
    return exit_status();
}

/* Test case */
static int check_banned(const char *str)
{
    const char *banned[] = {
        "[\t\r\n ]strcpy[\t\r\n ]*(",
        "[\t\r\n ]sprintf[\t\r\n ]*(",
        "[\t\r\n ]gets[\t\r\n ]*(", 
        "[\t\r\n ]alloca[\t\r\n ]*("
    };

    unsigned short i; 

    if (str == NULL)
        return FAIL;

    for (i = 0; i < sizeof(banned)/sizeof(banned[0]); i++){
        if (match(banned[i], str)){
            return FAIL;
	}
    }
    return PASS; 
}
