overloading "=" operator, with volatile

struct _HCFS
{
DWORD HCFS;
struct _HCFS operator=( int val);
};

struct _HCFS hcfs;
hcfs = 1;

this is OK,
but I define
volotile struct _HCFS hcfs;
hcfs =1;

there is alway a compilation error, saying "no overloading function found
for left operator struct _HCFS.

any suggestions?
thanks

You shouldn't use names that start with underscore - they're reserved for
the implementation.

Operator = should return _HCFS&.

For a voliatile verion:

volatile _HCFS& operator=(int val) voliatle;
