Parameters:

Returns:

One of two public output functions.

Parameters:

One of two public output functions.

Returns xsputn(__s,__n). The effect is to write __s[0] through __s[__n-1] to the output sequence, if possible.

template<typename _CharT, typename _Traits = char_traits<_CharT>> int_type std::basic_streambuf< _CharT, _Traits >::sungetc () [inline], [inherited]¶

Returns:

template<typename _CharT , typename _Traits = std::char_traits<_CharT>> virtual int __gnu_cxx::stdio_sync_filebuf< _CharT, _Traits >::sync (void) [inline], [protected], [virtual]¶

template<typename _CharT, typename _Traits = char_traits<_CharT>> virtual int_type return std::basic_streambuf< _CharT, _Traits >::traits_type::eof () [protected], [virtual], [inherited]¶

Note:

template<typename _CharT , typename _Traits = std::char_traits<_CharT>> virtual int_type __gnu_cxx::stdio_sync_filebuf< _CharT, _Traits >::uflow () [inline], [protected], [virtual]¶

Fetches more data from the controlled sequence.

Returns:

Informally, this function does the same thing as underflow(), and in fact is required to call that function. It also returns the new character, like underflow() does. However, this function also moves the read position forward by one.

Reimplemented from std::basic_streambuf< _CharT, _Traits >.

template<typename _CharT , typename _Traits = std::char_traits<_CharT>> virtual int_type __gnu_cxx::stdio_sync_filebuf< _CharT, _Traits >::underflow () [inline], [protected], [virtual]¶

Fetches more data from the controlled sequence.

Returns:

Informally, this function is called when the input buffer is exhausted (or does not exist, as buffering need not actually be done). If a buffer exists, it is refilled. In either case, the next available character is returned, or traits::eof() to indicate a null pending sequence.

For a formal definition of the pending sequence, see a good text such as Langer & Kreft, or [27.5.2.4.3]/7-14.

A functioning input streambuf can be created by overriding only this function (no buffer area will be used). For an example, see http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt11ch25.html

Multiple character extraction.

Parameters:

Returns:

Fills __s[0] through __s[__n-1] with characters from the input sequence, as if by sbumpc(). Stops when either __n characters have been copied, or when traits::eof() would be copied.

It is expected that derived classes provide a more efficient implementation by overriding this definition.

Returns:

Writes __s[0] through __s[__n-1] to the output sequence, as if by sputc(). Stops when either n characters have been copied, or when sputc() would return traits::eof().
