RPC Overview

A Remote Procedure Call (RPC) is a defined call to M code that runs on a VistA M Server. A client application, through the RPC Broker, can make a call to the VistA M Server and execute an RPC on the server. This is the mechanism through which a client application can:

  • Send data to a VistA M Server.
  • Execute code on a VistA M Server.
  • Retrieve data from a VistA M Server.

An RPC can take optional parameters to do some task and then return either a single value or an array to the client application. RPCs are stored in the REMOTE PROCEDURE file (#8994).
