std::ends: std::ends

NAME

std::ends - std::ends

Synopsis

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
