Write a complete message to a stream asynchronously.
Defined in header
template< class AsyncWriteStream, bool isRequest, class Body, class Fields, class WriteHandler> void-or-deduced async_write( AsyncWriteStream& stream, message< isRequest, Body, Fields >& msg, WriteHandler&& handler);
This function is used to write a complete message to a stream asynchronously using HTTP/1. The function call always returns immediately. The asynchronous operation will continue until one of the following conditions is true:
This operation is implemented in terms of zero or more calls to the stream's
and is known as a composed operation. The program
must ensure that the stream performs no other writes until this operation
completes. The algorithm will use a temporary
http::serializer with an empty chunk
decorator to produce buffers.
The stream to which the data is to be written. The type must support the AsyncWriteStream concept.
The message to write. The object must remain valid at least until the handler is called; ownership is not transferred.
The handler to be called when the operation completes. Copies will be made of the handler as required. The equivalent function signature of the handler must be:
void handler( error_code const& error, // result of operation std::size_t bytes_transferred // the number of bytes written to the stream );
Regardless of whether the asynchronous operation completes immediately
or not, the handler will not be invoked from within this function.
Invocation of the handler will be performed in a manner equivalent
