Parameters

filename

Filename to load.

        {
            using namespace std;

            // Open stream
            basic_ifstream<Ch> stream(filename, ios::binary);

            stream.seekg(0);   
            
            // Load data and add terminating 0
            m_data.resize(size + 1);
            stream.read(&m_data.front(), static_cast<streamsize>(size));
