How much C++ knowledge I need for glfw?

[abtahi tajwar]

Where would I found a good tutorial for opengl3.3 glfw(not video tutorial)

How much knowledge should I have in C++. I'm asking that because I'm not understanding clearly by reading its tutorials, like its explaining me how to buffur, but I dont even know what buffer is, its telling me about how to add pol and waiting events but I dont know what are they also not understanding some syntaxes like
void error_callback(paramiters)
{
....
}
glfwSetErrorCallback(error_callback)

But how could I use a function(error_callback) with out any paramiters and why I'm using it in "glfwseterrorcallback" lots of problems like it..

What should I do now for understanding them?

GLFW is a bunch of functions and other stuff that allows you to create a window etc, you dont need to know a lot of c++ to know how to use these functions. If you want to learn about GLFW, You can do that from their documentation - http://www.glfw.org/documentation.html

And here is a getting started thing for glfw, that includes an explanation on how error_callback works - http://www.glfw.org/docs/latest/quick.html

Edit 2:

void error_callback(paramiters)
{
    // You cant just say you're not understand the syntax like we can read your mind
    // What syntax are you not understanding? This is just a function with parameters?
}

Where would I found a good tutorial for opengl3.3+ glfw(not video tutorial)

I've already answered this question for you in one of your previous posts but I'll do it again.

http://learnopengl.com/

This teaches you pretty much all the basic techniques/syntax/functions you need to know in modern opengl (3.3+), and plenty of advanced ones, the guide also uses glfw. There are also lots of other good modern opengl tutorials, but they dont use glfw.

Note: This thread doesn't belong in the window programming section, you should probably move it or next time choose a more appropriate section.

Which section should I choose?

[TarikNeaj]

Your question is unclear, I sent you multiple links and each link has sections.

Actually I dont know clearly what I'm not understanding and what should understand, everything is totally unclear to me.. Thats why my questions are being uncleared.. I'm sorry for that..
