If used on an input stream it will flush any input that was read and buffered, but not yet delivered. For example, you call fgetc() to get one byte, but the library may actually read 20 bytes from the stream, although it only delivers the first to you. If so, calling fflush() discards the 19 bytes that the library has buffered. In your case though, you are calling PeekNamedPipe which is an OS function. It tells you that there is input, but it is in the system buffer not in the library's. So, calling fflush() has nothing to do because you haven't read any data yet.
