Una cadena terminada en cero byte (ONA) es una secuencia de bytes distintos de cero seguido de un byte con valor cero (el carácter nulo de terminación). Cada byte en una cadena de bytes codifica un carácter de un conjunto de caracteres. Por ejemplo, la matriz de caracteres {'\x63','\x61','\x74','\0'} es una celebración de la NTBS "cat" cadena en la codificación ASCII .
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.
