How to create a multisampled FBO in OpenGL?

[qian-o]

I have been using GLES before, and there is a glFramebufferTexture2DMultisampleEXT function that can help me quickly create a multisampled FBO. But when I switch to GL, I couldn't find a similar function.

I searched for relevant tutorials, and most of them use Blit to handle multisampled FBO. I think this operation will create multiple FBOs and textures, and performing a Blit operation every frame will be slow. (perhaps this is my misunderstanding)

So, is there a more convenient way to achieve multi-sampling?
