arguments where the format string is obtained from user data, or otherwise difficult to verify statically. Example usage: printf(fmtcheck(user_format, standard_format), arg1, arg2); checks the format string user_format for consistency (same number/order/ type of format operators) with standard_format. If they differ, standard_format is used instead to avoid potential crashes or security violations. Obtained from: NetBSD Reviewed by: -arch
