Previous: Perl interface
This section describes some of the basic features of the library in
comparison with the VAX version:
- The library provides only read access.
- Only VAX binary GSD files can be read.
- Bad values in the file are converted to PRIMDAT bad
values[6], which differ from the traditional VAX/GSD bad
values. (This conversion is in memory only, the file itself is unchanged.)
- Type conversion is possible only between numeric types (including
logical). Numeric to character or character to numeric conversion is not
provided by the library.
