data are the double precision data contained between
the specified addresses within the specified file.
1) If `begin' is zero or negative, the error SPICE(DAFNEGADDR)
2) If the begin > end, the error SPICE(DAFBEGGTEND)
3) If the file associated with `handle' is not of the native
binary file format this routine signals the error
4) If `handle' is invalid, routines in the call tree of dafrda_c
signal an appropriate error.
The principal reason that DAFs are so easy to use is that
the data in each DAF are considered to be one long contiguous
set of double precision numbers. You can grab data from anywhere
within a DAF without knowing (or caring) about the physical
records in which they are stored.
This routine has been made obsolete by the routines dafgda_c and
dafgsr_c. This routine is supported for reasons of backward
compatibility only. New software development should utilize
dafgda_c or dafgsr_c.
The following code fragment illustrates the use of dafrda_c
to read data from an imaginary array. The array begins with a
directory containing 11 epochs. Each pair of epochs bounds
an interval, and each interval is covered by a set of eight

end = ic;
dafrda_c ( handle, begin, begin+10, epochs );
for ( i = 0; i < 10; i++ )
if ( ( et > epochs[i] )
&& ( et < epochs[i+1] ) )
offset = ic + 11 + (i - 1) * 8;
dafrda_c ( handle, offset+1, offset+8, elements );
