Question

I’m trying to pass a member variable into a template. In example, if I have the following:

struct MyStruct
{
MyType MyMember;
}

How can I do something like:

MyType MyVar = MyTemplate<MyStruct, &MyStruct::MyMember, MyType>();


I tried to search around and didn’t find anything that explain exactly how to achieve that… Sorry if that is a stupid question, I’m pretty new to c++…

Any help is welcome!

Here goes something:

template< typename Class, typename MemberType, MemberType Class::*Member >
struct my_template;

and you can use it like this:

my_template< MyStruct, MyType, &MyStruct::MyMember > _;
