Key functions:

• main(): source/server/core_server.cpp
  • Parses command line options
  • Reads configuration file
  • Sets up signal handler / console control handler
  • Daemonizes (if applicable)
• RunServer(): source/server/core_server.cpp
  • Manages the server's lifetime
  • Owns service objects
  • Builds and runs the server
  • Waits for server shutdown (triggered by signal handler)
  • System test equivalent: source/tests/system/device_server.cpp
• register_all_services(): generated/register_all_services.cpp
  • Creates the resource repositories used to store session handles
  • Calls service registration functions
  • Collects service objects in a vector<shared_ptr<void>>
• ${driver}::register_service(): generated/*/register_service.cpp
  • Creates the library object used to call the driver DLL
  • Creates the service object
  • Registers the service with the gRPC server builder

The core server uses shared_ptr to manage the lifetime of the services, libraries, and resource repositories. This diagram shows a simplified view of the graph of shared_ptr references.
