Video for Windows DK Setup Script Function VflatdPresent

SUMMARY

The Microsoft Video for Windows Runtime setup script (SETUP.MST) contains calls to a number of functions. All the functions are documented except for the VflatdPresent() function.

The VflatdPresent() function detects whether the line "device=dva.386" exists in the SYSTEM.INI file. If the line doesn't exist, the CreateSysIniKey() function creates the entry. This code is necessary to avoid the possibility of having two identical entries in the SYSTEM.INI file, which would result in a warning being generated during setup. The DVA.386 file is the virtual device driver that provides direct video access internally to Video for Windows.
