This may work even better! If this works faster than the method I
implemented, I'd much rather use it in place of my own. I will have to do
some experimenting with it, but if it generates unique filenames under load
(multiple programs all using the same call simultaneously) without flaw,
than I will definitely adopt the FPC method sysutils.GetTempFilename - for
code management, portability reasons, and the likelihood of a performance
boost to what I have devised and am using now.
Perhaps the original author who was trying to do this for GO32 (whose email
request was a few years old now Nov, 2001 I think) was unaware of this
GetTempFileName call, it didn't exist then, or it did not work for him in
GO32, at least there are "home made" alternatives one could devise with a
little creativity that can accomplish the same thing as I have done.
