To unlock or not to unlock...that is the question. My interpretation is
that it's OK to lock them at the beginning (as long as you unlock them at the
end) if you're going to be allocating all your memory at once. It's when you
lock big chunks down and then try to allocate more that you're in trouble --
if the OS needs to shuffle things to make enough contiguous space.
Especially if you don't use MoveMHi before locking them down.
Am I totally wrong here? Please tell me if so.
Since we're asking beginner's questions...I've got a couple -- What is
"MultiFinder memory" and how do you allocate it? I've been told by numerous
people that modules that need tons of memory can take advantage of
MultiFinder memory, but I can't find any references to it in my resources
(mainly the Apple Developer CD-ROMs and the MacTech Cd-ROM).
My other question has to do with the "synchFlag" bit in AD. What is the
proper way to use this? I thought I was doing it right, but then I ran one
of my animated modules on a PowerBook and noticed horrendous flicker not
present in BSI modules.
Now...I've gotten the embarrassment of acknowledging that I don't know the
answer to these two fundamentals...back to my network headaches.
