ge) &rarr; int</b><br/>
    Returns the length of the error message of the LPeg lexer or Lua lexer error
    that occurred (if any), or stores the error message into the given buffer.</p>

    <p>If no error occurred, the returned message will be empty.</p>

    <p>Since the LPeg lexer does not throw errors as they occur, errors can only
    be handled passively. Note that the LPeg lexer does print all errors to
    stderr.</p>

    <p>Usage:</p>
