C library for gRPC

Question

I have not found support of the C language on grpc.io. Are there any "unofficial" libraries supporting gRPC in C?

My whole project is in C. I'm seeing a few options:

• rewrite in C++ (inefficient, just to support gRPC)
• write module talking gRPC in C++ and mix with C (I guess this is doable, but quite ugly?)
• find a C library implementing gRPC API etc.
• write my own using the core library from grpc.io (have no idea, how difficult it's going to be)

Unoffical library:

• github.com/juniper/grpc-c "C implementation of gRPC layered on top of core library"
