If the remaining gas is less than 5 * len(x), then no gas is subtracted, the code of the created contract becomes the empty string, but this is not treated as an exceptional condition - no reverts happen. -How do I use ``.send()``? -========================= - -If you want to send 20 Ether from a contract to the address ``x``, you use ``x.send(20 ether);``. -Here, ``x`` can be a plain address or a contract. If the contract already explicitly defines -a function ``send`` (and thus overwrites the special function), you can use ``address(x).send(20 ether);``. - -Note that the call to ``send`` may fail in certain conditions, such as if you have insufficient funds, so you should always check the return value. -``send`` returns ``true`` if the send was successful and ``false`` otherwise. - What does the following strange check do in the Custom Token contract? ====================================================================== |
