Do-nothing constructor. |
Once <open> is called, multiple asynchronous <writes>s can started using this class. A ACE_Asynch_Write_Stream::Result will be passed back to the <handler> when the asynchronous write completes through the <ACE_Handler::handle_write_stream> callback.

This starts off an asynchronous send. Up to <message_block->total_length()> will be sent. <message_block>'s <rd_ptr> will be updated to reflect the sent bytes if the send operation is successful completed. Return code of 1 means immediate success and number_of_bytes_sent is updated to number of bytes sent. The <ACE_Handler::handle_write_dgram> method will still be called. Return code of 0 means the IO will complete proactively. Return code of -1 means there was an error, use errno to get the error code. Priority of the operation is specified by <priority>. On POSIX4-Unix, this is supported. Works like <nice> in Unix. Negative values are not allowed. 0 means priority of the operation same as the process priority. 1 means priority of the operation is one less than process. And so forth. <signal_number> is a no-op on non-POSIX4 systems. Implements ACE_Asynch_Write_Dgram_Impl. |
