Hey guys, this has to do with many libraries so I put it here instead. I'd like to know, if I use direct3d, directinput, or any other library from microsoft, would I have to pay microsoft in someway? I'm currently using OpenGL and GLFW for input/window handling/multithreading/etc., but I'm attracted to directinput, and for sound I could use OpenAL, but I'm attracted to directaudio, and I wanted to know this first before messing with any, thanks guys!
