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.

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.

Parameters

os

-

reference to output stream

Return value

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

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
