fn get_fix_screeninfo(device: &File) -> Result<FixScreeninfo, FramebufferError>

Creates a FixScreeninfo struct and fills it using ioctl.

fn get_var_screeninfo(device: &File) -> Result<VarScreeninfo, FramebufferError>

Creates a VarScreeninfo struct and fills it using ioctl.

fn put_var_screeninfo(device: &File, screeninfo: &VarScreeninfo) -> Result<i32, FramebufferError>

fn set_kd_mode(kd_mode: KdMode) -> Result<i32, FramebufferError>
