std::basic_streambuf<CharT,Traits>::basic_streambuf
From cppreference.com
< cpp | io | basic streambuf
protected: basic_streambuf(); |
(1) | |
|
protected
:
basic_streambuf( const basic_streambuf& rhs) ; |
(2) | (since C++11) |
1) Constructs the
basic_streambuf object, initializes the six pointer members (eback(), gptr(), egptr(), pbase(), pptr(), and epptr()) to null pointer values, and the locale member to
std::locale()
2) Constructs a copy of rhs, initializing the six pointers and the locale object with the copies of the values held by rhs. Note that this is a shallow copy: the pointers of the newly-constructed basic_streambuf are pointing into the same character array as the pointers of rhs
Both constructors are protected, and are only called by the concrete streambuf classes, such as std::basic_filebuf, std::basic_stringbuf, or std::strstreambuf
Parameters
| rhs | - | a streambuf object to copy |
Notes
Until C++11, it was unspecified whether basic_streambuf or any of its derived classes is CopyConstructible (LWG issue 421
