Re-allocate memory on the heap
Source position: heaph.inc line 99
function ReAllocMem( |
var p: pointer; |
Size: PtrInt |
):pointer; |
ReAllocMem resizes the memory pointed to by P so it has size Size. The value of P may change during this operation. The contents of the memory pointed to by P (if any) will be copied to the new location, but may be truncated if the newly allocated memory block is smaller in size. If a larger block is allocated, only the used memory is initialized, extra memory will not be zeroed out.
Note that P may be nil, in that case the behaviour of ReAllocMem is equivalent to Getmem.
