warning C28165: The function pointer of class does not match the function class

A function pointer has a __drv_functionClass annotation that specifies that only functions of a particular functional class should be assigned to it. In an assignment or implied assignment in a function call, the source and target must be of the same function class, but the function classes do not match.

Example

The following code example elicits this warning.

IoSetCancelRoutine(MyStartIo);

The following code example avoids this warning.

IoSetCancelRoutine(MyCancelRoutine);
