How to use a public function of a class?

[王__云飞]

In my C++ program, I use some public functions of some classes in the offload region.I use the statement __attribute ((target(mic))) before the functions. But I found that the program crushed when it goes through the offload regions which use public functions of classes.

So I wonder that if there are some special things to care when I use functions of a class? Is my way correct? 

Thank you very much.

My understanding is that classes are all-or-nothing.   The entire class needs to be marked for offload, even if you are only using a few methods in it.
