NVIC check if IRQ is enabled

Question

Hi, 
 as far as I see, I can enable or disable external interrupts using NVIC_EnableIRQ() and NVIC_DisableIRQ . Is there a method to check if a specified external interrupt is currently enabled or disabled? 
 Is this done by NVIC_GetActive() ? 
 Thanks,
Tamas

No, NVIC_GetActive() will only return 1 when the interrupt is currently being serviced (directly or preempted by a higher priority). So it should always return zero in main() funtion. 
 You are probably looking for the NVIC_GetEnableIRQ() function. 
 Note that both functions do not work with negative IRQn like SysTick.
