.SH DESCRIPTION
.PP
.I Get_data
reads data from a binary file. This file is expected to contain a stream
of bytes, short integers, long integers, floating values, or double precision
floating values. The
.I dtype
argument indicates the type of data in the file; it may be 'b', 'w', 'l', 'f',
or 'd'.
.I Npoints
values are read from the file, converted to double by
.I get_ddata,
to float by
.I get_fdata,
and returned in the
.I data
array.
.SH DIAGNOSTICS
If a read error occurs,
.I get_data
prints an error message on the error output and exits.
.SH BUGS
Ideally, an error status should be returned on error and the program should
be allowed to determine whether to exit.

.SH EXPECTED CHANGES
Fix the flaw described in "BUGS".
