Hutzelman) Newsgroups: comp.sys.apple2 Subject: Re: what to do with the Text Tools (multitasking tools) Message-ID: Date: 30 May 91 00:06:02 GMT References: <767@generic.UUCP>, <53393@apple.Apple.COM> Organization: Carnegie Mellon, Pittsburgh, PA Lines: 10 In-Reply-To: <53393@apple.Apple.COM> I have something that uses it, archived on disk here. It's the context switching code from LWP/GS, which uses both the toolbox's and GS/OS's busy flags to make sure it doesn't do a switch in the middle of an OS or tool call. I'd be happy to upload the current version of the code somewhere if it will help you guys eliminate toolbox bugs. Now that I have my machine back, I'll be finishing some changes I wanted to make, including saving/restoring the current GrafPort so that more than one process can draw. .
