# std::ends

From cppreference.com
< cpp‎ | io‎ | manip

Defined in header `<ostream>` |  |
template< class CharT, class Traits > std::basic_ostream<charT,traits>& ends( std::basic_ostream<CharT, Traits>& os ); |  |

Inserts a null character into the output sequence `os` as if by calling os.put(CharT()).

This is an output-only I/O manipulator, it may be called with an expression such as out << std::ends for any `out` of type std::basic_ostream.

### [edit] Notes

This manipulator is typically used with std::ostrstream, when the associated output buffer needs to be null-terminated to be processed as a C string.

Unlike std::endl, this manipulator does not flush the stream.

### [edit] Parameters

os | - | reference to output stream

### [edit] Return value

`os` (reference to the stream after insertion of the null character)

### [edit] Example

Run this code

    #include <cstdio>
    #include <strstream>
    int main()
    {
        std::ostrstream oss;
        oss << "Sample text: " << 42 << std::ends;
        std::printf("%s\n", oss.str());
        oss.freeze(false); // enable memory deallocation
    }

Output:

    Sample text: 42
