Hi i just have a curios question that i have been wanting to know...

is it possible for one to get a job for any company with the knowledge of sdl??

i know that is just a library for basic graphics and input.

another thing is can i make money selling a game made in sdl to some publisher if its good?

Your game will not be "made in SDL". It might use SDL for a certain task, such as capturing input or managing threads. Now, both of those things are easy to do with SDL and they both require quite a bit of work without SDL, but they are still only a very small part of all the code that goes into making a game.

As for getting a job with the knowledge of SDL, not really sure what you mean. Knowing JUST SDL will not get your far. Does knowing SDL help? Sure. A lot of companies use it. Eg. Valve uses it for their cross platform stuff. Actually, IIRC, the original author of SDL works for Valve.

In general, you do not get a programming job because you know any particular API, you get a programming job because you can show you have a solid understanding of the concepts of programming, and is a fast learner.

It's expected that you can pick up and run with any API thrown at you.

So just practice using whatever, and write lots of code.
