Thanks for your answer, Mr. POUTIGNAT wasn't wrong but your approach is
a little bit faster (but still slightly wrong...)

I got the answer today. What to do is the following :

       if ( you_need_wireframe )
        {
                pfEnable( PFEN_WIREFRAME);
        }
       else
        {
                pfDisable( PFEN_WIREFRAME);
        }

I got some friends who told me that it works fine...
