I would like to be able to read any and all characters that are currently in the console buffer, without knowing how many are in the buffer. If there's one character in the buffer, it should read that one character and return. If there's 100 characters in the buffer, it should read those 100 characters and return. If NO characters are in the buffer it should return immediately without reading anything. It should NEVER stop running (engage in a blocking operation) while waiting for something to read. Is it possible to do this with the console API functions?
