Allocates memory for sending data to an instance of XceedZip or XceedCompression object. You cannot use any other memory allocation function for for this purpose.
When you want to specify a memory buffer to compress through the ZippingMemoryFile event, you must set the pbDataToCompress parameter to a buffer allocated with XzAlloc. The instance will free the buffer when it’s done compressing it.
When you want to call the XcCompress, XcUncompress or XcCalculateCrc functions, you must allocate the source buffer with XzAlloc, or use a buffer that was previously returned by a previous call to one of those functions. A buffer created with XzAlloc must be freed with XzFree, except when the instance frees it.
