Ciarán, CreateProcess() is not a shell -- it will pass all arguments (including your redirection specifiers) to the program. This is not a Cygwin-specific problem -- you would have gotten the same errors with a pure Windows executable. You might want to read up on the arguments to CreateProcess on MSDN (especially the input/output handles in the STARTUPINFO structure). If you have further questions, a Windows-specific list might be a better venue.
