  2. Null-terminated string - Wikipedia

    en.wikipedia.org/wiki/Null-terminated_string

    In computer programming, a null-terminated string is a character string stored as an array containing the characters and terminated with a null character (a character with an internal value of zero, called "NUL" in this article, not same as the glyph zero).

  3. Buffer overflow - Wikipedia

    en.wikipedia.org/wiki/Buffer_overflow

    When available, the strlcpy library function is preferred over strncpy which does not null-terminate the destination buffer if the source string's length is greater than or equal to the size of the buffer (the third argument passed to the function). Therefore A may not be null-terminated and cannot be treated as a valid C-style string.

  4. C string handling - Wikipedia

    en.wikipedia.org/wiki/C_string_handling

    This is partly due to the mistaken belief by many C programmers that strncat and strncpy have the desired behavior; however, neither function was designed for this (they were intended to manipulate null-padded fixed-size string buffers, a data format less commonly used in modern software), and the behavior and arguments are non-intuitive and ...

    en.wikipedia.org/wiki/C_standard_library

    string-manipulation routines, including strcpy() and strcat(), for lack of bounds checking and possible buffer overflows if the bounds are not checked manually; string routines in general, for side-effects, encouraging irresponsible buffer usage, not always guaranteeing valid null-terminated output, linear length calculation; [b]

  6. String (computer science) - Wikipedia

    en.wikipedia.org/wiki/String_(computer_science)

    In terminated strings, the terminating code is not an allowable character in any string. Strings with length field do not have this limitation and can also store arbitrary binary data . An example of a null-terminated string stored in a 10-byte buffer , along with its ASCII (or more modern UTF-8 ) representation as 8-bit hexadecimal numbers is:

  8. Null character - Wikipedia

    en.wikipedia.org/wiki/Null_character

    It is often abbreviated as NUL (or NULL, though in some contexts that term is used for the null pointer). In 8-bit codes, it is known as a null byte . The original meaning of this character was like NOP —when sent to a printer or a terminal , it has no effect (some terminals, however, incorrectly display it as space ).

  9. C++ string handling - Wikipedia

    en.wikipedia.org/wiki/C++_string_handling

    The std::string type is the main string datatype in standard C++ since 1998, but it was not always part of C++. From C, C++ inherited the convention of using null-terminated strings that are handled by a pointer to their first element, and a library of functions that manipulate such strings.
