haiku/headers/private/app/LinkMsgReader.h
Axel Dörfler 75936a02e4 BPortLink now has a FlushWithReply() method itself.
BPortLink::AttachString() now accepts a length argument, and will no longer
send a terminating null byte; LinkMsgReader::ReadString(), however, will
make sure the string read is null terminated.
Changed client communication code to use FlushWithReply() instead of Flush()
and GetNextReply() - there were many bugs and shortcomings in the code, I
hope I've fixed them all.
Converted ClientFontList.cpp to our coding style (but not completely, the
class members are missing).
Some more cleanup - I hope Adi will adopt our coding style one day!
