ZeroMQ

Safe handle for unmanaged libraries. See http://msdn.microsoft.com/msdnmag/issues/05/10/Reliability/ for more about safe handles.

Utility class to wrap an unmanaged shared lib and be responsible for freeing it.

This is a managed wrapper over the native LoadLibrary, GetProcAddress, and FreeLibrary calls on Windows and dlopen, dlsym, and dlclose on Posix environments.

Dynamically look up a function in the dll via kernel32!GetProcAddress or libdl!dlsym.

Delegate type to load Raw name of the function in the export table. A delegate to the unmanaged function. Thrown if the given function name is not found in the library. GetProcAddress results are valid as long as the dll is not yet unloaded. This is very very dangerous to use since you need to ensure that the dll is not unloaded until after you're done with any objects implemented by the dll. For example, if you get a delegate that then gets an IUnknown implemented by this dll, you can not dispose this library until that IUnknown is collected. Else, you may free the library and then the CLR may call release on that IUnknown and it will crash.

When receiving messages a socket shall prepend a message part containing the identity of the originating peer to the message before passing it to the application. When sending messages a ZMQ_ROUTER socket shall remove the first part of the message and use it to determine the identity of the peer the message shall be routed to. If the peer does not exist anymore the message shall be silently discarded.
