If while configuring the EXTI line I use:

EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Rising_Falling

how can I know in my interrupt if a rising of falling triggered it?

void EXTI1_IRQHandler(void)
  if ( RisingEdge )
  else if ( FallingEdge )
  { ....

How can I do anything similar to this?

Thank you for your time
