=== Icon Legend===
* [[image:Att.gif]]: It seems that these functions were not implemented on the OS/2 4.5 Toolkit.
* [[Image:Conf.gif]]: These functions were documented on the Addendum of the OS/2 4.5 Toolkit.
* [[image:Vraag.gif]]: More information is required on this function.


== Legacy Functions ==
===Advanced VIO===
This are the legacy functions of the Control Program Interface API. This functions are supposed to be replaced by the newer ones, but some of these are still required for older programs to work or because some newer functions weren't implemented correctly.
