How to get the:
heap_id
heap_base

of the AllocatedMemory ?

*mem_id = AllocateMemory(1024)

heap_base = *mem_id ?

Not help.

How to get heap_base & heap_addr to use with the:
*mem_id = HeapReAlloc_(
?

Use API or PB, ReAllocateMemory should do it.

Work effectively only through:
function HeapReAlloc(
hHeap: THandle;
dwFlags: DWORD;
lpMem: Pointer;
dwBytes: DWORD
): Pointer; stdcall;

So I'm asking how to get hHeap and lpMem, for use in PureBasic
by calling
HeapReAlloc_(

I do not need approval, I need a working example

Code: Select all

Define *mem = HeapAlloc_(GetProcessHeap_(), $08, 100)
Define *mem2
If *mem
  *mem2 = HeapReAlloc_(GetProcessHeap_(), $08, *mem, 200)
EndIf

10x a lot!

This work:

Code: Select all

*mem = AllocateMemory(100)
PokeL(*mem+$0000, $12345678)

*mem = HeapReAlloc_(GetProcessHeap_(), $08, *mem, 200)
Debug StrU(MemorySize(*mem))
Debug PeekL(*mem+$0000)

doesn't work on my pc, but this works:

Code: Select all

*mem = AllocateMemory(100)
PokeL(*mem + $0000, $12345678)

*mem = ReAllocateMemory(*mem, 200)
Debug StrU(MemorySize(*mem))
Debug PeekL(*mem + $0000)

May be into the PureBasic exist constant the Heap ID of task, like #PB_HEAP ?
