__raise

Emphasizes the call site of an event.

__raise method-declarator;

Remarks

From managed code, an event can only be raised from within the class where it is defined. See event (Visual C++) for more information.

The keyword __raise causes an error to be emitted if you call a non-event.

Example

// EventHandlingRef_raise.cpp
struct E {
 __event void func1();
 void func1(int) {}
 void func2() {}
 void b() {
 __raise func1();
 __raise func1(1); // C3745: 'int Event::bar(int)': 
 // only an event can be 'raised'
 __raise func2(); // C3745
 }
};
int main() {
 E e;
 __raise e.func1();
 __raise e.func1(1); // C3745
 __raise e.func2(); // C3745
}
