Description

• Returns 1 if new keyboard information is available, 2 if mouse information is available, otherwise it returns 0.
• Must be called before reading any of the other mouse functions and before reading _CINP.
• To clear all previous input data, read _CONSOLEINPUT in a loop until it returns 0.
• Not available in Linux or macOS.
