The fact that your program works does not mean it is correct.

In my case the warnings indicated a problem in my code, i.e. the warnings
were justified, they just didn't help much to clearly identify the exact
location of the problems in my code.

I guess the data you read with 'fscanf' is not compatible with the
format you specified in 'fscanf' call, but to verify this guess you need
to publish data in the file pointed to by FID.
