A null-terminated byte string (NTBS) is a possibly empty sequence of nonzero bytes followed by a byte with value zero (the terminating null character). Each byte in a byte string encodes one character of some character set. For example, the character array {'\x63', '\x61', '\x74', '\0'} is an NTBS …

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. WebCopies the values of num bytes from the location pointed by source to the memory block pointed by destination.Copying takes place as if an intermediate buffer were used, allowing the destination and source to overlap. The underlying type of the objects pointed by both the source and destination pointers are irrelevant for this function; The result is a binary copy …
