Pure C client

[zing...@gmail.com]

Hello all.

I'm pretty new to grpc and library implementations. I need to integrate grpc client to my pure c embedded application. Can you please advise, is it possible to use gprc library from pure c, without C++ layer?

As I see, for now, there is only Cpp in the examples.

Thank you in advance,

Best regards,

Anton

You can refer to gRPC Core's header file: https://github.com/grpc/grpc/tree/master/include/grpc.

gRPC Core exposes C API, but it contains large number of C++ code. The gRPC Core API is designed to serve language wrappers (like C++, Python, Ruby) and it could be challenge to develop application upon.

It's also worth noting that the C-core API is not really a public API, since it's aimed at language integrators, not at applications.  In particular, we do not guarantee any backward compatibility in the C-core API; it may change in breaking ways from release to release.  Currently, we do publish gRFCs (see https://github.com/grpc/proposal/) when this happens, but that policy could change in the future.
