Call the driver specific ioctl function.
unsigned char __fastcall__ mouse_ioctl (unsigned char code, void* data);
The function calls the IOCTL entry in the mouse driver, which is driver specific. The
codeparameter will choose between different IOCTL functions, and the
datadepends on code. The function returns an error code. The purpose of this function is to allow for driver specific extensions. See the documentation for a specific mouse driver for supported ioctl calls.
- Calling this function is non portable, because each driver may implement different ioctl calls (or none at all).
- The function is only available as fastcall function, so it may only be used in presence of a prototype.
