W8051: Non-volatile function 'function' called for volatile object (C++)

(Command-line option to suppress warning: -w-nvf)

In C++, a class member function was called for a volatile object of the class type, but the function was not declared with volatile following the function header. Only a volatile member function can be called for a volatile object.

For example, if you have

Copy Code

      class c
      {
      public:
        f() volatile;
        g();
      };
      volatile c vcvar;

it is legal to call vcvar.f(), but not to call vcvar.g().
