Can anyone point me to some sample code that shows how to allocate a dos
buffer (below 1 meg). I want to understand how to do things this way and
not rely on tb. 
For instance:
  allocate buffer below 1 meg - size -32k
  fill buffer with data and read it back
  store actual buffer address in say regs.r.ax and regs.r.bx 
  free buffer

I looked at __dpmi_allocate_dos_memory but it gets you a selector and I dont
know what to do to convert that to a pointer

Thanks
Eric
