Quoted manipulator
(C++14)
Defined in header
<ostream>
template< class CharT, class Traits >
std::basic_ostream <CharT, Traits>& ends( std::basic_ostream <CharT, Traits>& os );
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 .
Contents
[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
