I don't know what gcc or clang command line option to use to require this.


If you declare the function with gcc's warn_unused_result attribute
the compiler will warn when you don't check the result.

For example:

    size_t strlcpy(char *dst, const char *src, size_t dstsize)
        __attribute__((warn_unused_result));
