Description
Use the sk_setTCAPHandler() function to organize the flow of TUSI and SUSI messages for your application.

This function does not affect the routing of any acknowledgment messages. This function is also available as skts_setTCAPHandler().
int sk_setTCAPHandler(int aStackID, int anSSN, void *aTag, HandlerFunc* aHandlerFunc);
int skts_setTCAPHandler(int aStackID, int anSSN, void *aTag, HandlerFunc* aHandlerFunc);
