I currently do this with SDL, but want to try GLFW for the same thing.

SDL_Init( SDL_INIT_VIDEO );
SDL_Flip( sdlscreen );
I have used GLFW for OpenGL projects successfully.

If you want to do software rendering you should use SDL or another similar
library. GLFW is not intended for this purpose.

GLFW does not provide framebuffer addresses to OpenGL. That is not how OpenGL
works. OpenGL is a standardised API intended primarily for hardware-
accelerated rendering; it’s not a software rendering API with direct access to
a framebuffer, like SDL is.
You should read about what OpenGL is if you intend to use it.
