Code examples

The following code example fails the check and will give a warning:

namespace {
// Test if word 'main' is in a string.
bool main(const char* s) {
 // ...
}
}

int main() {
  return 0;
}

The following code example passes the check and will not give a warning about this issue:

 // ...
}
}

int main() {
  return 0;
}
