Where <device spec.> is device specification (i.e. DSK0:),
<contig> receives size of largest contigous block,
<total> receives total number of blocks free.
<contig> and <total> must be mapped as floating point
variables, i.e.:
MAP1 contig,F,6
MAP1 total,F,6
If an error occurs (bad device spec., etc.) contig is set to
0 and the file system error code is returned in total.
Note that the device driver for the specified device must be loaded
into memory and that there must be sufficient memory available in the
BASIC impure area to hold a 24 byte result table (from DSKFRE), a DDB,
and a 512 byte disk buffer.
