CryptGenRandom isn't in WinRT https://github.com/mirror/boost/issues/5#issuecomment-77984515

• There's no reason to use vector. An array should
  work just fine, since the size is known at compile
  time
• Is there a reason to go through DataReader instead of
  just calling CryptographicBuffer::CopyToByteArray?
• I'd prefer not to use auto. Boost.Random is still
  C++03 compatible.
• When was WINAPI_FAMILY_PARTITION defined? I don't
  want to break compatibility with older compilers.
  I still test with VC9.
• Similarly, will it work with MinGW or clang-cl?
• Where are these components coming from? I notice
  that you #ifdefed out the #include <windows.h>.
• Can these functions fail? What happens if they do?
  The MSDN documentation is nearly useless.

Is there a reason to go through DataReader

i fixed it

When was WINAPI_FAMILY_PARTITION defined?

i fixed the config to the same as https://github.com/boostorg/asio/blob/master/include/boost/asio/detail/config.hpp so it should work

I'd prefer not to use auto.

there's no winrt compiler that doesn't support auto

will it work with MinGW or clang-cl?

do they have an rt compiler?

Where are these components coming from?

the namespaces comes from /ZW

Can these functions fail?

doesn't seem so

edit: maybe they can throw an exception? should they be in a try/catch?

Okay.

My concern wasn't so much compiling for WinRT
as the use of an unknown macro breaking desktop
compilation.

k i get it

By array I meant unsigned char[sizeof(result)].
Also, I'd rather not put any kind of WinRT
configuration in the header when it's only
used by random_device.cpp.

done

By array I meant unsigned char[sizeof(result)].

it doesn't accept that type

https://msdn.microsoft.com/en-us/library/windows.security.cryptography.cryptographicbuffer.copytobytearray.aspx

Type: array of Number [JavaScript] | System.Byte[] [.NET] | Platform::Array [C++]

The most recent version of the WinRT #ifdefing
is broken:

compile-c-c++
......\bin.v2\libs\random\build\msvc-12.0\debug\threading-multi\random_device.obj
random_device.cpp
......\libs\random\src\random_device.cpp(117) : error C2653:
'CryptographicBuffer' : is not a class or namespace name

u need to add /ZW boostorg/build#62

I'm NOT building for WinRT.

k so winapifamily.h is included for all vc 2013 builds then https://github.com/jp9000/OBS/blob/master/extras/winapifamily.h#L34

[swatanabe]

I've rebased this and applied it to develop.
