ReAllocMem function
Re-allocate memory on the heap.
Declaration
function ReAllocMem(var p: pointer; Size: PtrUInt): pointerDescription
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.
