int main( )  
{  
   int         aidev;         /* Audio input device handle */  
   SC_TSINFO   sc_tsinfo;     /* Time slot information structure */  
   long        scts;          /* TDM bus time slot */  
   /* Open audio input device aiB1 */  
   if ((aidev = ai_open("aiB1")) < 0) {  
      /* process error */  
   }  
   /* Fill in the TDM bus time slot information */  
   sc_tsinfo.sc_numts = 1;  
   sc_tsinfo.sc_tsarrayp = &scts;  
   /* Get TDM bus time slot connected to transmit of audio input device */  
   if (ai_getxmitslot(aidev, &sc_tsinfo) < 0) {  
      /* process error */  
   }  
   else {  
      printf("%s is transmitting on TDM time slot %d", ATDV_NAMEP(aidev), scts);  
   }  
   /* Close audio input device */  
   if (ai_close(aidev) < 0) {  
      /* process error */
