I have a design question. Is it better to define separate classes for SENDING and RECEIVING. Or, is it better to define a single Thread class? I like the idea of a single Thread class because it is easier to share a queue which can be locked by mutex. Design Option #1 (Separate): mySendThread = new SendThread(); // Have thread properti...
It has been a few years since I did any development for PCs (I usually do embedded software). At that time I was highly proficient with (Borland, now CodeGear) C++ Builder. Time has moved on, C++ Builder has become extremely expensive and there are alternatives (MSVC stufio, NetBeans, QtCreator, maybe even Eclipse with the right plugi...
