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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

           2      Returns buffer size for graphics capture.

Comments
 
The InquireSave (or InquireGrab) function is responsible for carrying out
any necessary initializations for the grabber the first time the function is
called. Windows calls either InquireGrab or InquireSave before any other
call to a grabber function (unless the InitScreen function is present).
