Webstrlen, strnlen_s. 1) Returns the length of the given null-terminated byte string, that is, the number of characters in a character array whose first element is pointed to by str up to and not including the first null character. The behavior is undefined if str is not a pointer to a null-terminated byte string.

WebCopies the first num characters of source to destination.If the end of the source C string (which is signaled by a null-character) is found before num characters have been copied, destination is padded with zeros until a total of num characters have been written to it. No null-character is implicitly appended at the end of destination if source is longer than num.
