SDL simple example

It can't get much simpler than this. I did notice one odd thing, when I tried to create errs to test my case error handling, SDL_Init(value), doesn't give a rat's derriere what value is passed. I mixed the code up a little to make it look pretty here and so if you copy it, be warned it isn't some file.c that I have compiled. It is just reference to say, "this is pretty simple" and this much code is enough to make a sound play. I got most of this from Grubby Games and then tested it, modified it, compiled it, and now I am going to use the information gained to create my own application that is a bit more elegant. So thanks to them at Grubby Games, as their code actually works and that is not always true for some sites. I also got information from the SDL wiki, a German SDL site and many others. I like to investigate the breadth and depth of the issues and this looks like the way to go for sound. I could do all the stuff in buffers and then send it to dsp, but I don't want to reinvent fire today, maybe next week.

Of course you would need several DEV headers and the libraries themselves,
but this isn't a kindergarten Linux or C example.*/
