You give it a filename and it will return a pointer to a C structure called Radar .
Radar contains all the information found in the input file.
You will notice that there are only two output routines. Output for UF and HDF are supplied because of the popularity of those two formats. This paper presents RSL from a science application developer's point of view. It will present some of the more useful routines and which fields in the Radar structure that will be important to you and it will attempt to cover some of the programming pitfalls associated with RSL usage. One of the most difficult hurdles to overcome is that RSL makes extensive use of pointer syntax.
