Communication

RedEdrPplService provides a pipe to interact with it:

#define PPL_SERVICE_PIPE_NAME L"\\\\.\\pipe\\RedEdrPplService"

Which is the pipeServer in control.cpp. It only receives ASCII commands. Like:

• start:<processname>: Observes
• stop: Indicate RedEdr.exe is being shutdown - disconnect PPL_DATA_PIPE_NAME
• shutdown: Shutdown the service (so the exe can be updated)

If RedEdr connects to this pipe, RedEdrPplService will automatically attempt to connect back to RedEdr's pipe:

#define PPL_DATA_PIPE_NAME L"\\\\.\\pipe\\RedEdrPplData"

It will only send the matching events to this pipe.
