IntPtr ContextHandle cannot be used

[ckohrt]

Hello,
I try to share the context between C# and C/C++ to get inproc working.

When I try in C#:
ZmqContext c = ZmqContext.Create();
IntPtr p2 = c.ContextHandle;

TA_StartReceive(p2);//C++ dll function

In C++:
TRADITIONALAPI_API void __stdcall TA_StartReceive(void* context)
{
void *socket = zmq_socket (context, ZMQ_REP);
int rc = zmq_bind (socket, "inproc://#1");
...
}

The socket is always NULL. Why?

Regards,
Christian
