residue_ranges.c
Purpose:
Extract residue ranges (serial numbers) from the list.
Input:
(1) Pointer to SelectS structure, where data will be stored.
(2) Pointer to the string with list of ranges.
Output:
(1) Some data added to SelectS structure.
(2) Return value.
Return value:
(1) Positive on success.
(2) Negative on failure.
