How to connect a C function into a class ( int wiringPiISR (int pin, int mode, void (*function)(void)) )

[JPannetier]

Hello ,

I'm using WiringPi librairy with my Raspberry Pi 3

I have a class Form_Trigger_Laser

My function to connect my interrupt from WiringPi

void Form_Trigger_Laser::InitWiringPiLaser()
{

wiringPiISR(1,INT_EDGE_FALLING,&Edge_Falling_Laser());

}

void Form_Trigger_Laser::Edge_Falling_Laser()
{
B_StatusLed=false;
ui->Widget_Led_Laser_Status->setStyleSheet("border-image:url(:/Ressource/red-led-off-md.png)");
SendLaserTrigger();
}

Nevertheless, the prototype of wiringPiISR is :
int wiringPiISR (int pin, int mode, void (*function)(void))

I can't connect at my function Class ...
How to connect : int wiringPiISR (int pin, int mode, void (*function)(void)) at Form_Trigger_Laser::Edge_Falling_Laser() ?

Thank you
Best regard

Hi
From Very fast look it seems like it wants a good old plain c call back?

void (*function)(void)

So you must use a global function or a static class function for it to like it.

The function must be

void FuncName(void)

So no return or parameter.

so void Form_Trigger_Laser::InitWiringPiLaser()
cannot be part of class. ( or must be static )
