Reading voltage -ADC

I'm using STM32 VL microcontroller.I need to read voltage i'm using timer 2 in interupt mode to read ADC value.below is my code.. wheneven ADCread value function is colled from TIM2 interrupt, i goes to  infine loop in while function..
Can any body tell me why its happening like that.or is that any alternate method to implement..??

int main()
NVIC_config(); // timer 2 interrupt

int ADCReadValue()
 ADC_RegularChannelConfig(ADC1, channel, 1, ADC_SampleTime_1Cycles5);
ADC_SoftwareStartConvCmd(ADC1, ENABLE);
// code hangs in this while loop
while(ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC) == RESET);
 return ADC_GetConversionValue(ADC1);

void TIM2_IRQHandler()
    if(TIM_GetITStatus(TIM@, TIM_IT_Update) != RESET)
        TIM_ClearITPendingBit(TIM2, TIM_IT_Update);
