I've attached a little patch that makes iostreams::code_converter flushable. It seems like it really should be. Is there any chance someone could look at this? I've included some test code as well that outputs the following. ********** OUTPUT BEFORE PATCH ********** main(): Sending 24 characters of data to output stream SinkDev::write(): Recieved 16 characters. main(): Calling a sync on the output stream main(): Sending 21 characters of data to output stream SinkDev::write(): Recieved 16 characters. main(): Asking for 24 characters of data from input stream SourceDev::read(): Sending 16 characters. SourceDev::read(): Sending 16 characters. main(): Calling a sync on the input stream main(): Asking for 9 characters of data from input stream SourceDev::read(): Sending 16 characters. main(): At end of test case SinkDev::write(): Recieved 13 characters. ********** OUTPUT AFTER PATCH ********** main(): Sending 24 characters of data to output stream SinkDev::write(): Recieved 16 characters. main(): Calling a sync on the output stream SinkDev::write(): Recieved 8 characters. main(): Sending 21 characters of data to output stream SinkDev::write(): Recieved 16 characters. main(): Asking for 24 characters of data from input stream SourceDev::read(): Sending 16 characters. SourceDev::read(): Sending 16 characters. main(): Calling a sync on the input stream main(): Asking for 9 characters of data from input stream SourceDev::read(): Sending 16 characters. main(): At end of test case SinkDev::write(): Recieved 5 characters. SinkDev::write(): Recieved 0 characters. SinkDev::write(): Recieved 0 characters. SinkDev::write(): Recieved 0 characters. ********** END ********** Notice that input functionality doesn't change but the output functionality does. The one cause for concern to me is that for some reason upon deconstruction the new flush() function is called a bunch of extras times. I'm not entirely sure why this is happening. -- Eddie Carle
