Answer 1

need to send a few bytes to video memory. What's the problem?

Answer 2

There are no standard graphics libraries in C, so the options are:
1. Use system functions (like Win32 API or X Window or higher level KDE types)
2. Use generic interfaces like OpenGL
3. Use third party graphics libraries like qt
4. Directly work with the hardware (if the application runs on bare metal, as a kernel driver or in an OS that allows you to directly address video memory)
