CID 12515 - SECURE_CODING
[VERY RISKY]. Using "sscanf" can cause a buffer overflow when done incorrectly. sscanf() assumes an arbitrarily large string, so callers must use correct precision specifiers or never use sscanf(). Use correct precision specifiers or do your own parsing.

127 int nDigits = 0;
