- /* args.h
- An abstract class to pass values to maplay and other worker
- threads.
- From the Win32 API, we can only pass one 32-bit value to a thread. This will
- be a pointer to a object of this class. The Args class contains the seeking
- control variables needed for both MPEG and MCI files.
- Added stop and done variables and functions for terminating the
- threads from outside.
- This class should be used to pass arguments to maplay(),
- and to initialize the Obuffer's. */
