Detailed Description

Framebuffer device header.

The sys/fb.h header defines structs and constants used by framebuffer devices, for example /dev/fb0. The primary way to use a framebuffer device is to first use IOCTL_FB_INFO to retrieve its width and height, then factoring in its format to get the total size in bytes of the framebuffer and finally using mmap to map it to the currently running processes address space.
