🔗

basic_filebuf<charT, traits>* rdbuf() const;

1

#

Returns: const_cast<basic_filebuf<charT, traits>*>(addressof(sb)).

🔗

native_handle_type native_handle() const noexcept;

2

#

Effects: Equivalent to: return rdbuf()->native_handle();

🔗

bool is_open() const;

3

#

Returns: rdbuf()->is_open().

🔗

void open( const char* s, ios_base::openmode mode = ios_base::in | ios_base::out); void open( const filesystem::path::value_type* s, ios_base::openmode mode = ios_base::in | ios_base::out); // wide systems only; see [[fstream.syn]](fstream.syn "31.10.1 Header <fstream> synopsis")

4

#

Effects: Callsrdbuf()->open(s, mode).

If that function does not return a null pointer calls clear(), otherwise callssetstate(failbit) (which may throwios_base​::​failure) ([iostate.flags]).

🔗

void open( const string& s, ios_base::openmode mode = ios_base::in | ios_base::out); void open( const filesystem::path& s, ios_base::openmode mode = ios_base::in | ios_base::out);

5

#

Effects: Calls open(s.c_str(), mode).

🔗

void close();

6

#

Effects: Callsrdbuf()->close() and, if that function returns a null pointer, callssetstate(failbit) (which may throwios_base​::​failure) ([iostate.flags]).
