I use Linux when I work from home, I'm forced to use a Mac at work (well, I boot up a virtual Linux OS), and I use Windows when I just want to goof around with my computer. So, while most of my work is done on Linux, it's imperative that my code work on all platforms; just because I could use any of the three. Traditionally, C required multiple versions of code, protected by #ifdefs. This often required multiple versions of code to be written, depending on the target system, target OS, and compiler being used. Clumsy and messy system. C++ too had similar shortcomings. When it came to writing multi-threaded code, I had to choose either Win32 or Posix, and once I made that choice, I was bound by it. Since those were the days when Ubuntu was driving me crazy, I chose Win32. Bad decision. Every single action that I attempted was compounded by the fact that Win32 is the worst API ever. How do I lock a mutex? Well, first I declare a handle, then declare a mutex, then define the...
