Basic C Client

A basic example of a data movement client written in C and CGo.

WARNING: The C client should not be used beyond rapid prototyping; The C++ client should be use long-term.

Generating client code

To generate the gRPC client interfaces from our .proto service definition, use the protoc protocol buffer compiler

$ make protoc

Running this command generate the following files in your current directory

• datamovement.pb-c.h, the header which declares your generated message classes
• datamovement.pb-c.c, which contains the implementation of your message classes

Creating the Client

Since there is no native C gRPC Client, this example uses the gRPC Go client with a CGo interface for interacting with the client.

$ make client.a

Compile and Run

Build the client

$ make client

Assuming you have a server running (i.e. ./server --simulated --socket=/tmp/nnf.sock), run the client

$ ./client
