std::ends - cppreference.com (original) (raw)

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

[edit] Return value

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

[edit] Example

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

Output:
