Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

The Microsoft Windows display grabbers provide the support that both
standard- and 386 enhanced-mode Windows needs to share the display with
non-Windows applications. WINOLDAP, which manages all non-Windows
applications, loads the display grabbers and calls grabber functions to
carry out tasks such as capturing the contents of the screen or managing
output from a non-Windows application.
