Hi,

I try to use the DosQueryFSInfo call to read
the media id of a floppy disk. The call should
return this (unique) id together with some
allocation information of the disk in the
FSALLOCATE struct. The online manual tells me,
that the sequence

  FSALLOCATE fsa;

  DosQueryFSInfo( 1,             // drive A:
                  1,             // retrieve allocation info
                  &fsa,          // address of retrieval buffer
	          sizeof( fsa)); // size of the buffer

should retrieve the information and the first 4 byte
in the structure should contain the media ID.

The call retrieves all other allocation inforamtion of the disk 
correct, only the media ID is always zero (which should only happen,
if format does not write one, as the mtools of my UNIX station do).

I've compiled the C++ code with emx-0.8d and use the header files
from the Toolkit for OS/2 2.0.

Is it my fault? Are there problems with emx?
Is there a bug in the system call? 

Any suggestions are welcome.

Thanks,

Lutz
