C++ (Cpp) safercopy Examples

Example #1

File: ex27_1.c Project: gastlygem/lcthw_ex

int main(int argc, char *argv[])
{
    // careful to understand why we can get these sizes
    char from[] = "0123456789";
    int from_len = sizeof(from);

    // notice that it's 7 chars + \0
    char to[] = "0123456";
    int to_len = sizeof(to);

    debug("Copying '%s':%d to '%s':%d", from, from_len, to, to_len);

    int rc = safercopy(from_len, from, to_len, to);
    check(rc > 0, "Failed to safercopy.");
    check(to[to_len - 1] == '\0', "String not terminated.");

    debug("Result is: '%s':%d", to, to_len);

    // now try to break it
    rc = safercopy(from_len * -1, from, to_len, to);
    check(rc == -1, "safercopy should fail #1");
    check(to[to_len - 1] == '\0', "String not terminated.");
