Provides a layer of compatibility for C.

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

template<typename _CharT , typename _Traits = std::char_traits<_CharT>> std::__c_file* const \fB__gnu_cxx::stdio_sync_filebuf\fP< _CharT, _Traits >::file ()\fC [inline]\fP

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.
