@var O_BINARY: the 'binary' mode flag on Windows, or 0 on other platforms, so it
may safely be OR'ed into a mask for os.open.

Internal method for quoting a single command-line argument.
@param s: an unquoted string that you want to quote so that something that
does cmd.exe-style unquoting will interpret it as a single argument,
even if it contains spaces.
@type s: C{str}
@return: a quoted string.
@rtype: C{str}

Quote an iterable of command-line arguments for passing to CreateProcess or
a similar API. This allows the list passed to C{reactor.spawnProcess} to
match the child process's C{sys.argv} properly.
@param arglist: an iterable of C{str}, each unquoted.
@return: a single string, with the given sequence quoted as necessary.

Formatter for Windows error messages.
@ivar winError: A callable which takes one integer error number argument
and returns an L{exceptions.WindowsError} instance for that error (like
L{ctypes.WinError}).
@ivar formatMessage: A callable which takes one integer error number
argument and returns a C{str} giving the message for that error (like
L{win32api.FormatMessage}).
@ivar errorTab: A mapping from integer error numbers to C{str} messages
which correspond to those erorrs (like I{socket.errorTab}).

Returns the string associated with a Windows error message, such as the
ones found in socket.error.
Attempts direct lookup against the win32 API via ctypes and then
pywin32 if available), then in the error table in the socket module,
then finally defaulting to C{os.strerror}.
