Bug 14600 - __gnu_cxx::stdio_sync_filebuf should expose internal FILE*

Description:

Last confirmed: 2004-04-07 03:06

Opened: 2004-03-16 09:45

Similar to the __gnu_cxx::stdio_filebuf<>::fd() member function, there should
be
a __gnu_cxx::stdio_sync_filebuf::c_file() member function which returns the
underlying FILE*.

With the advent of __gnu_cxx::stdio_sync_filebuf<> that feature becomes needed
for interfacing to good ol' Unix machinery.  A patch was proposed on
<http://gcc.gnu.org/ml/libstdc++/2004-02/msg00379.html>.  It even appears that
consensus had been reached:
<http://gcc.gnu.org/ml/libstdc++/2004-02/msg00189.html>. Due to the trivial
nature of the patch, it should also be considered a candidate for 3.4.x.

This is not a regresssion and therefore not a show-stopper for 3.4.1 -- or any
other release.
