c urgent probleme de capture d'evenemet - Communauté Informatique NDFR.net

salut
je travaille sur vc++, j'utilise une console , j'ai une fonction de prototype suivant ;
GAP_Perform_Inquiry(BluetoothStackID,itGeneralInquiry, 0, 0, 10, 5,GAP_EventCallback,(unsigned long)0);
avec GAP_EventCallback est un pointeur sur fonction qui s'active des qu'il ya un evenement par exemple (faire un inquiry)

cette fonction est definit en bas , mais mon probleme que
Result = GAP_Perform_Inquiry(BluetoothStackID,itGeneralInquiry, 0, 0, 10, 5,GAP_EventCallback,(unsigned long)0);
me retourne un Result >0 (c a dire succes ) mais l'evenement ne se declenche pas et je sais pas pkoi ,j'ai essaie avec le debugueur mais apparament il n'entre pas a l'interieur de la fonction GAP_EventCallback et GAPEventData pointe sur un zero ;vous n'avez pas une solution c urgent
