/// Due to [platform-specific behavior], the exit code for this example will be

/// ```no_run
/// use std::process;

/// process::exit(0x0f00);

However from the text above, line process::exit(0x0f00); should be changed to process::exit(0x0100); . On Windows, all 32 bits of the exit code is available. See the document of ExitProcess() for more details. (The parameter of ExitProcess() is a UINT, which maps to a C unsigned int on Windows platforms, which usually is a 32-bit unsigned integer today. The 32-bit 0x0f00 is 3840, not 256.)
