MEMORY

Steal temporary memory


Just a small point:
Do not confuse "temporary memory" with "system heap memory." They are two different things, in two different locations. To get a block of system heap memory, you use a statement like this:

h& = FN NEWHANDLE _sys (size&)

But to get a block of temporary memory, you need to call the Toolbox function TempNewHandle, like this:

h& = FN TempNewHandle&(size&, @OSErr%)

where FN TempNewHandle& is defined like this:

'--------------------------------------------------------
LOCAL FN TempNewHandle&(size&, OSErrAddr&)
  ` CLR.L -(SP)
  ` MOVE.L ^size&,-(SP)
  ` MOVE.L ^OSErrAddr&,-(SP)
  ` MOVE.W #$001D,-(SP)
  ` DC.W $A88F
  ` MOVE.L (SP)+,^handle&
END FN = handle&
'--------------------------------------------------------

The available Temporary Memory is often (but not always) larger than the available System Heap space, so you will probably have a better chance of getting a block if you get it from Temporary Memory.
