How to correct my code in case of an abnormal branch

The below function is called by a few events.


int sendDeviceEvent(int idx, char type){
 int result;
 char *buff;

 if(type == TYPE_REG)
 sendInfoToSlave(buff, sizeof(sRegPoll));
 else if(type == TYPE_128)
 sendInfoToSlave(buff, sizeof(s128Poll));
 else if(type == TYPE_INV)
 sendInfoToSlave(buff, sizeof(sInvPoll));


 return waitInfoFromSlave(idx);


If this function is called by EVENT_A(sendDeviceEvent(1, TYPE_REG)), sendInfoToSlave(buff, sizeof(sRegPoll)) is executed normally.


But If this function is called by EVENT_B(sendDeviceEvent(1, TYPE_REG)),  sendInfoToSlave(buff, sizeof(sRegPoll)) is not executed. That is, is not branched to sendInfoToSlave().


Which point should I check? (IAR, ST32F2xx series)
