opengl-es glUseProgram() arugments

Question

My first time trying out openGL on iOS. I have compiled the source and now I can only run the program, but how can I pass in arguments to that program for more dynamic behavious? Or do I have to compile from source every time with the argument embedded in the source?

I am looking for something like glUseProgram(myProgram, arg1, arg2);

Thanks

You cant use that function like that.

What you are looking for, is using uniforms and attributes, each is specified differently. It is a very extensive subject so I suggest you try reading this:
