Doxygen/C++: Global namespace in namespace list

Can I show the global namespace in the namespace list of the documentation generated with Doxygen? I have some functions which are extern "C", they app开发者_JAVA百科ear in the documentation of the header file that declares them, but not in the namespace list and it gives the impression that they are not really there...

As far as i know, this feature is still missing from Doxygen. One work-around that is not overly verbose is to use @defgroup MyGlobals and put the extern "C" functions in that group:

/*! @ingroup MyGlobals
 * @{ */

// ... functions

/*! @} */

This adds the functions in an entry called MyGlobals on the tab Modules.

This blog entry presents a work-around using xrefs, but i personally find it too verbose.
