Hi all,

I am trying to use std.mmfile on Win 7 64 bit, compiler dmd 32 2.059

MmFile memoryFile = new MmFile("test");

I receive this error:
std.exception.ErrnoException@std\mmfile.d(270):  (No error)

which is a little bit confusing for beginner. Am I using it in wrong way?

I am trying to achieve this functionality: http://msdn.microsoft.com/en-us/library/windows/desktop/aa366551(v=vs.85).aspx

Shared memory is created by another program, so I only need to access it.

After inspection of code in mmfile.d I am not sure if there is even possible to map file to virtual memory (INVALID_HANDLE_VALUE) with mmfile,
lastly I am missing c function OpenFileMapping in windows.di too.

Thanks a lot for any hints.

Best Ondrej

I found out that OpenFileMapping is not needed and CreateFileMapping is sufficient. I managed to code this with std.c.windows only however MmFile is not working even with simplest examlple maybe a bug under win 7?

Possible. Feel free to file a bug report or create a pull request.
