*
|
|
* @param token The @ref completion_token that will be used to produce a
|
|
* completion handler, which will be called when the write completes.
|
|
* Potential completion tokens include @ref use_future, @ref use_awaitable,
|
|
* @ref yield_context, or a function object with the correct completion
|
|
* signature. The function signature of the completion handler must be:
|
|
* @code void handler(
|
|
* const asio::error_code& error, // Result of operation.
|
|
* std::size_t bytes_transferred // Number of bytes written.
|
|
* ); @endcode
|
|
* Regardless of whether the asynchronous operation completes immediately or
|
|
* not, the completion handler will not be invoked from within this function.
|
|
* On immediate completion, invocation of the handler will be performed in a
|
|
* manner equivalent to using asio::post().
|
|
*
|
|
* @par Completion Signature
|
|
* @code void(asio::error_code, std::size_t) @endcode
|
|
*
|
|
* @note The write operation may not transmit all of the data to the peer.
|
|
* Consider using the @ref async_write function if you need to ensure that all
|
|
* data is written before the asynchronous operation completes.
|
|
*
|
|
* @par Example
|
|
* To write a single data buffer use the @ref buffer function as follows:
|
|
* @code
|
|
* pipe.async_write_some(asio::buffer(data, size), handler);
|
|
* @endcode
|
|
* See the @ref buffer documentation for information on writing multiple
|
|
* buffers in one go, and how to use it with arrays, boost::array or
|
|
* std::vector.
