There are some C libraries out there which do this C wrappers around the C++ Core using the dynamic library libgrpc. Here is an older example , the newer one is possibly a fork from this.
Language support such as Python is a wrapper and is using cython basically a C interface to the library.
gRPC is written in C++ and it is possible to call C++ libraries from C. I suggest you look up
extern "C"
Here is a stackoverflow thread
