Hi all
How do I find out the leftover amount of storage memory on
my device? I've tried the following code (on the Emulator)
but the amount returned never changes, despite extensive
"read record data + decompress it + resize record + write
record back" operations. Obviously a bad case of RTFM, or
is the Emulator debug session misleading me?
Thanks in advance
Alex

UInt32 freeStorage = GetFreeStorageMem (0);
...
UInt32 GetFreeStorageMem (Int16 cardNo)
{
Int16 i;
Int16 nCards;
UInt16 heapID, flags;
UInt32 totalStorage = 0;
// Iterate through each card to support devices with multiple cards.
if (cardNo == MEM_ALL_CARDS)
nCards = MemNumCards ();
else if (cardNo >= 0)
nCards = cardNo + 1;
else
return 0;
for (cardNo=0; cardNo<nCards; cardNo++)
{
// Iterate through the heaps on a card
for (i=0; i<MemNumHeaps (cardNo); i++)
{
// Obtain the ID of the heap.
heapID = MemHeapID (cardNo, i);
flags = MemHeapFlags (heapID);
if (! MemHeapDynamic (heapID) && (flags & 0x0001))
totalStorage += MemHeapSize (heapID);
}
}
return totalStorage;
}
