This means that WINSCW device-level code must be substantially different from that used by native targets.</p> <p>First, you will need substantial conditional compilation. Device drivers will need full testing under both WINSCW and ARM targets. In general, a WINSCW device driver is best considered as a separate project from a corresponding native target device driver.</p> <p>Usually, in order to implement this kind of code, you will also need to access Win32 libraries. Specify them using <filepath>.mmp</filepath> specifications such as:</p> <codeblock id="GUID-2CF2B4E3-8FA7-5B0A-8FE5-AA27FCEE6453" xml:space="preserve">start wins
win32_library kernel32.lib gdi.lib
