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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

InfoContext ends
 
The INFOCONTEXT structure is a global structure shared by all the grabbers
and may be considered the non-Windows application version of the GDIINFO
structure for Windows drivers.

Comments
 
INFOCONTEXT is essentially a superset of the GRABINFO structure returned by
the GetInfo entry point. GRABINFO has sufficient reserved space so that this
information may be made available to the Windows layer in the future as well
as allow for more members being added if needed.
