Detailed Description

   template<typename _CharT, typename _Traits = std::char_traits<_CharT>>class __gnu_cxx::stdio_filebuf< _CharT,
       _Traits >
       Provides a layer of compatibility for C/POSIX.

       This GNU extension provides extensions for working with standard C FILE*'s and POSIX file descriptors. It
       must be instantiated by the user with the type of character used in the file stream, e.g.,
       stdio_filebuf<char>.

Constructor & Destructor Documentation

   template<typename _CharT , typename _Traits  = std::char_traits<_CharT>> __gnu_cxx::stdio_filebuf< _CharT,
       _Traits >::stdio_filebuf () [inline]
       deferred initialization

       Definition at line 66 of file stdio_filebuf.h.

   template<typename _CharT , typename _Traits > __gnu_cxx::stdio_filebuf< _CharT, _Traits >::stdio_filebuf (int
       __fd, std::ios_base::openmode __mode, size_t __size = static_cast<size_t>(BUFSIZ))
       Parameters:
           __fd An open file descriptor.
           __mode Same meaning as in a standard filebuf.
           __size Optimal or preferred size of internal buffer, in chars.

       This constructor associates a file stream buffer with an open POSIX file descriptor. The file descriptor
       will be automatically closed when the stdio_filebuf is closed/destroyed.

       Definition at line 129 of file stdio_filebuf.h.

   template<typename _CharT , typename _Traits > __gnu_cxx::stdio_filebuf< _CharT, _Traits >::stdio_filebuf
       (std::__c_file * __f, std::ios_base::openmode __mode, size_t __size = static_cast<size_t>(BUFSIZ))
       Parameters:
           __f An open FILE*.
           __mode Same meaning as in a standard filebuf.
           __size Optimal or preferred size of internal buffer, in chars. Defaults to system's BUFSIZ.

       This constructor associates a file stream buffer with an open C FILE*. The FILE* will not be
       automatically closed when the stdio_filebuf is closed/destroyed.

       Definition at line 145 of file stdio_filebuf.h.

   template<typename _CharT , typename _Traits > __gnu_cxx::stdio_filebuf< _CharT, _Traits >::~stdio_filebuf ()
       [virtual]
       Closes the external data stream if the file descriptor constructor was used.

Member Function Documentation

   template<typename _CharT , typename _Traits  = std::char_traits<_CharT>> int __gnu_cxx::stdio_filebuf<
       _CharT, _Traits >::fd () [inline]
       Returns:
           The underlying file descriptor.

       Once associated with an external data stream, this function can be used to access the underlying POSIX
       file descriptor. Note that there is no way for the library to track what you do with the descriptor, so
       be careful.

       Definition at line 110 of file stdio_filebuf.h.

   template<typename _CharT , typename _Traits  = std::char_traits<_CharT>> std::__c_file*
       __gnu_cxx::stdio_filebuf< _CharT, _Traits >::file () [inline]
       Returns:
           The underlying FILE*.

       This function can be used to access the underlying 'C' file pointer. Note that there is no way for the
       library to track what you do with the file, so be careful.
