I don't get your point... CDROM_GetStatusCode is called with:
* 0 as parameter when previous operation was succesfull, and nothing happens
* -1, if the previous operation went wrong, and the goal of the function 
is to transform the Unix errno into a Win32 status code
so, being called with -1 is normal, it may miss some unix => win32 mappings

A+
