| <A NAME="sec4"><H3>Description</H3></A> |
| <P>The object <B><I>cerr</I></B> controls output to a stream buffer associated with the object <B><I>stderr</I></B> declared in <SAMP><cstdio></SAMP>. By default, the standard C and C++ streams are synchronized, but you can improve performance by using the <B><I><A HREF="ios-base.html">ios_base</A></I></B> member function <SAMP>synch_with_stdio</SAMP> to desynchronize them. </P> |
| <A NAME="sec5"><H3>Formatting</H3></A> |
| <P>The formatting is done through member functions or manipulators. See <B><I><A HREF="cout.html">cout</A></I></B> or <B><I><A HREF="basic-ostream.html">basic_ostream</A></I></B> for details.</P> |
