Problem : Argument cannot be negative @ 1165.
Diagnostic : Real issue.
Rationale : len can be assigned a negative value @ 1162;
len is passed as an unsigned argument @ 1165.
Resolution : Refactor variable's types:
- Use ftello instead of ftell to avoid using long.
- Assert ftello result is safely convertible to size_t.
- Introduce variable read_size to avoid using i (int).
