34 * The strnlen() function returns the number of characters in the string
35 * pointed to by s, not including the terminating '\0' character, but at most
36 * maxlen. In doing this, strnlen() looks only at the first maxlen characters
37 * at s and never beyond s+maxlen.
39 * The strnlen() function returns strlen(s), if that is less than maxlen, or
40 * maxlen if there is no '\0' character among the first maxlen characters
45 strnlen(const char *string, size_t maxlen)
