SEI CERT C Coding Standard (8)     Page: EXP12-C. Do not ignore values returned by functions     Page: FIO34-C. Distinguish between characters read from a file and EOF or WEOF     Page: DCL09-C. Declare functions that return errno with a return type of errno_t     Page: API09-C. Compatible values should have the same type     Page: INT10-C. Do not assume a positive remainder when using the % operator     Page: STR31-C. Guarantee that storage for strings has sufficient space for character data and the null terminator     Page: EXP20-C. Perform explicit tests to determine success, true and false, and equality     Page: ERR05-C. Application-independent code should provide error detection without dictating error handling
