Member Function Documentation

void* DownloadOpParam::operator new ( size_t stSize ) [inline]

This function allocates a block of memory to create a new SimpleCCObject derived thingy. This does not throw an exception, but returns NULL in the event of a failure. In debug builds it also keeps track of all allocations and will give a dump of all reamining blobs of memory when camelot exits.
