Brian,
Here's the function I use:
void
GetAvailMemory (UInt32* totalMemP, UInt32* freeMemP)
{
// Declare local variables.
UInt32 totalMemory = 0; // Total memory.
UInt32 availMemory = 0; // Available memory.
UInt16 numHeaps = 0; // Number of heaps to traverse.
UInt16 i = 0; // Iterator.
UInt16 heapID; // Identifier for each heap.
UInt32 maxChunk = 0; // Max chunk size (per heap).
UInt32 freeMemory = 0; // Free memory (per heap).
// Get the number of heaps.
numHeaps = MemNumHeaps (0);
// Traverse the heaps.
for (i = 0; i < numHeaps; i++)
{
// For each heap...
// Get the heap identifier.
heapID = MemHeapID (0, i);
// Check if the heap is dynamic.
if (MemHeapDynamic (heapID))
{
// Heap is dynamic.
// Get amount of free memory (and size of max chunk).
MemHeapFreeBytes (heapID, &freeMemory, &maxChunk);
// Add free memory
availMemory += freeMemory;
// Add heap size to total.
totalMemory += MemHeapSize (heapID);
}
}
// Set out-params.
*totalMemP = totalMemory;
*freeMemP = availMemory;
// Return.
return;
}
Checking all the heaps may be overkill, but it works.
Hope this helps,
Greg
