... this one is even smaller. Plus it uses the familiar strlen() function:size_t strnlen(const char *string, size_t max_count) { return strlen(string) < max_count ? strlen(string) : max_count; }
Please do not use that implementation. The major goal of strnlen is to avoid looking beyond &string[max_count]. strlen(string) looks all the way to the end, which may be very much longer than max_count; and which may cause SIGSEGV by running into a memory page that does not exist before the terminating '\0' is found. [Besides, some compilers do not recognize that "strlen(string)" need not be evaluated twice.] --
