STM CircleOS forum / Function pointer: how does it work with circleOS ?

Hello,

I need a function to register an handler :

void SetHandler(u32 handler)
{
    MyHandler = handler;
}

Next I would like to call that function using something like this :

(void (*)(char)) (MyHandler)(c);

But, it doesn't compile

Can someone give me an example ?

Thank you in advance

move some parenthesis

((void (*)(char)) MyHandler)(c)

Casts are always right-to-left. What you wrote is the cast of function call result.
