Re: Palm ZIRE dynamic heap size

[Nicolas Pabion]

IF you check the Palm SG PluggedIn FAQ, you'll see it has121KB of dynamic
heap (assuming device was just hard-reset).

Ron,

Yes, I should have said "maximum".  My larger point was that the vendor
determines the allocation between storage and dynamic, which is fixed.

And that to me is one of the reasons a drawlist callback is preferable to a list
stored in dynamic memory.  Testing under low memory conditions is a good idea,
and programs like Memory Hog make it easy to do so.

The two of you are talking about 2 different things.  Although total
dynamic heap size is fixed by the hardware vendor, the amount of 
available
dynamic memory is not, as it may be affected not only by "hacks", but by
display depth, network driver status, whether any OS upgrades have been
installed, background sound threads on newer models, etc. etc.

Because of this, it is important to test an application with much less
dynamic heap available than the default amount available on a clean idle
handheld after a cold boot.

Say i'm downloading a DB file to the zire to be used in a project, what are
the size limitations on such a file?

Thought i'd chime in.

No. Available memory depends on memory use. It's not
a fixed number.

Bullshark,

Wrong.  It is a number fixed by the manufacturer.  Adding applications or
database records has *no* affect on the number.  Running enabled hacks may
reduce the size though.

Out of the 2MB total memory, the dynamic size of this device is 121KB.

I'd recommend using Memory Hog to test applications in low memory situations.
It is a freeware app which lets you "hog" storage and / or dynamic memory for
purposes of testing.  It also reports what is the total and currently available
size of each on the app at that point in time.
