How do you set a pixel in the screen in Windows without call APIs?

[NairadFaivth]

Anybody can tell me if it is posible to set a pixel in the screen or in a device context without call APIs?

It depends on your environment.

Do you have a Console application or a standard Windows application ?
Within a console you can call the appropriate interrupt (see the famous list of Ralf Brown).

Within a standard Windows Application, I don't know how API's can be bypassed, and moreover, I don't see why it would be of any use to do so, for there are already a wide range of good APIs: GDI, GDI+, OpenGL, DirectX.
