C++ RPC

Open-source C++ projects categorized as RPC

RPC stands for Remote Procedure Call In the context of programming. In distributed computing, a remote procedure call is when a computer program causes a procedure to execute in a different address space, which is coded as if it were a normal procedure call, without the programmer explicitly coding the details for the remote interaction.
