Detailed Description

This class provides implementation for <ACE_Asynch_Write_File_Result> for POSIX platforms.

This class has all the information necessary for the handler to uniquiely identify the completion of the asynchronous write.

This class differs slightly from <ACE_Asynch_Write_Stream::Result> as it calls back <ACE_Handler::handle_write_file> on the handler instead of <ACE_Handler::handle_write_stream>. No additional state is required by this class as <ACE_Asynch_Result> can store the offset.
