My program crashed on this absent library function. Do not see it even in documentation while it is was OK just 3 years back. What's to do with this?

Dan,

See Appendix A. "Functions ported from DBOS"
page 429+ of clearwin.pdf (Feb 2000)

The replacement is :
CREATE_GRAPHICS_REGION@ etc.

Thanks, John, somehow I missed two things: the change itself and the documentation notes about it.

GET_SCREEN_BLOCK@ is an old DBOS routine that can be accessed from salflibc.dll (i.e. 32 bits) because it is "hard-wired" to a Win32 replacement function.

The recommended replacement is GET_SCREEN_DIB@ which has the same arguments except that they are 32 bit values rather than 16 bit values.

GET_SCREEN_DIB@ is exported by clearwin64.dll. The Win32 replacement mentioned above is not currently exported by clearwin64.dll.

'elo 'elo I smell confusion round the corner if this isn't clearly documented everywhere it needs to be or it'll be whirling back like a boomerand a la the 'what's a handle' posts

When's a next major documentation update scheduled for Paul ?
(that's a re-wok, consolidation, of the whole documentation packahìg not just version updates or fixes/clarifications which I know are ongoing.
There myst have been some level of planning/preparation done in the last 4 years I've been on the list ?

John,

It's simpler than that. The graphics facilities provided for DOS with the DBOS extender were completely supplanted by Clearwin+a very long time ago. I went to the launch of Clearwin, which was around 1992. A handful of the DBOS graphics routines were also provided to ease the transition. But that was a quarter century or more ago, and we move on.

There's nothing to stop someone like Dan writing a routine for himself, using the obsolete name (but without the @) which internally uses the new(er) routines. If such a person was public-spirited, they would post it on the forum!

Eddie
