Can I write programs using NTs Posix API?
Don’t even bother trying to use this. It’s the bare minimum of Posix compliance and doesn’t offer much functionality. For example, there is no sockets support or integration with the real Win32 API. It’s only there to help NT win sales in tenders where Posix support is mandatory (i.e. governments) The win32 console API is close enough to Posix functionality that many Posix apps should be compilable within the Win32 subsystem -which is exactly what the Gnu/win32 project does.
