Potential format string problem (CWE-134). Make format string constant.

Does not check for buffer overflows when copying to destination [MS-banned]
(CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
easily misused).

If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
