CID 12516 - SECURE_CODING
[VERY RISKY]. Using "sprintf" can cause a buffer overflow when done
incorrectly. Because sprintf() assumes an arbitrarily long string, callers
must be careful not to overflow the actual space of the destination. Use
snprintf() instead, or correct precision specifiers.
212 sprintf (name, "screenshot%d.png", number);
