Actaully Mem[x] is valid from 0 to MemSize - 1, which should be
>= currentsize. Which should have been obvious from that big
post I sent with the entire unfinished class so far.
So in other words I should do something like this:
IMem::IMem(const long AllocBytes) // default constructor
{
CurrentSize = 0;
MemSize = 0;
Mem = NULL;
temp = NULL;
try //
{
if (AllocBytes <= __LoMemBlock__)
{
MemSize = __LoMemBlock__;
}
else // >__LoMemBlock__
{
i = (AllocBytes / __HiMemBlock__) + 1;
MemSize = i * __HiMemBlock__;
while (MemSize < AllocBytes)
{
i++;
MemSize = i * __HiMemBlock__;
}
}
CurrentSize = AllocBytes;
Mem = new BYTE[MemSize + 1];
// ALBERTOS Change ^^^
}
catch (...)
{
delete [] Mem;
Mem = NULL;
CurrentSize = 0;
MemSize = 0;
Enterprise();
MessageBox(hiwind,"IMem Constructor Threw an Exception,"REALLY
bad",MB_OK);
// Call Panic Save HERE
Excelsior();
throw;
}
}
