Description
Waits for process signals and forks child processes.
WaitAndFork stalls the invoking process and forks child processes when signals are sent to it from an external source. Forked child processes will provide a return value of EWaitAndForkResult::Child, while the parent process will not return until IsEngineExitRequested() is true (EWaitAndForkResult::Parent) or there was an error (EWaitAndForkResult::Error) The signal the parent process expects is platform-specific (i.e. SIGRTMIN+1 on Linux).
