Ein null-terminierte Byte-String (NTB) ist eine Folge von null Byte von einem Byte mit dem Wert Null (das abschließende Nullzeichen) gefolgt. Jedes Byte in einem Byte-String kodiert ein Charakter einiger Zeichensatz. Zum Beispiel, das Zeichenarray {'\x63','\x61','\x74','\0'} ist ein NTBs die String "cat" in ASCII-Codierung .

Original:

A null-terminated byte string (NTBS) is a 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 holding the string "cat" in ASCII encoding.
