// TODO(flysand): ioctl
/*
Control devices. The ioctl syscall is a bit special because
its argument is usually a pointer to some driver-specific structure.
The request value is device-specific. Consult your LibC implementation's
ioctls.h file to learn more. The returned value of ioctl *may* be an error
code value instead of a memory address depending on the request type.
Available since Linux 1.0.
