PipeStuffer is a real-time i/o redirection wrapper for console programs. It uses named pipes for interprocess communication. PipeStuffer is based on RTConsole, but is designed to work around some quirky behavior that exist with consoles in Windows 10. To use, simply put the compiled executable in a known place. If you wanted the real-time output from a program called target.exe, instead of calling CreateProcess(NULL, "path/to/target.exe --opt1 arg 1", ...), you would create a named pipe, and pass the name to PipeStuffer like
CreateProcess("NULL, /path/to/pipe-stuffer.exe [PIPE NAME] path/to/target.exe --opt1 arg1", NULL, NULL, FALSE, ...)
where [PIPE NAME] is only the trailing part of the named pipe name, i.e. //./pipe/[PIPE NAME]. You should set bInheritHandles argument of CreateProcess to FALSE.
PipeStuffer uses a console screen buffer for communication with the target program so that output is not buffered. Any Windows console inherited by PipeStuffer is immediately dropped with FreeConsole(), and output from the target program will come through a named pipe. This prevents spurious behavior associated with Windows 10 implementation of consoles.
Note: When running your parent program in a Windows Command Prompt, sometimes you can correct the issues PipeStuffer solves by setting the Windows Command Prompt settings to use legacy mode. Sometimes you can't.
