I have written a tool that provides a (relatively) "high-level" access
to GSL by using an input text file. You can see that same rewritten
using my tool and reading the data from a textfile example here

The tool, which is GPLv3+, can be obtained here

If you still need to read the a two-columns text file into two C
arrays, you should be searching on stackoverflow or so.
