hi how can i convert a refence to a poiner ?

here is the method :

void Foo(const std::string& s,...)
const std::string* a = s ; //here we will do the conversion.

va_list args;


I tried the following but none of these works :

1) const std::string* a = s ;

error C2440: 'initializing' : cannot convert from std::string' to 'const std::string *'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called.

2) const std::string* a = &s ;

compiles, but when run "args" has random junk values
e.g an int passed has value 12300000 instead of 1000.

3) const std::string* a = *s ;

error C2100: illegal indirection

Here what i have done and works, but i am forced to use pointer.

1) int Foo(const std::string* s,...);

OK but user has to call it this way : Foo( &string("MYSTRING") , 1000 )
Which is complecated but works.

2) int Foo(const std::String s,...);

OK but it is slow, user has to wait for the string to get copy constructed.

so is there a workaround ?

thank you for your patience,
