for_each(blah, blah, PROBLEM), need some help :)

Hi,

im having trouble getting the syntax right for this situation, ive searched everywhere and all the instructions of found im having trouble relating to what im trying to achieve.

class Foo {
 public:
  void blah(void);
  void memFunc(ptr* arg);
  list<ptr*> myList;
};
 
void Foo::blah(void) {
 for_each(myList.begin(), myList.end(), &Foo::memFunc);
}
 
void Foo::memFunc(ptr* arg) {
 //do stuff with arg and this
}
 
 

ie. i want to apply the memFunc from the instance of Foo that is doing blah() to each of that instance's myList members.

but i dont know how to tell the compiler that i want the instance that is having blah called to be the instance that applies its memFunc. i couldnt get "this" to work and i was crashing the compiler with some of my attempts hehe

currently it just wont compile with the error message:
c:\program files\microsoft visual studio 8\vc\include\algorithm(29) : error C2064: term does not evaluate to a function taking 1 arguments
source.cpp(##) : see reference to function template instantiation '_Fn1 std::for_each<std::list<_Ty>::_Iterator<_Secure_va lidation>,void(__thiscall Foo::* )(ptr *)>(_InIt,_InIt,_Fn1)' being compiled
with
[
_Fn1=void (__thiscall Foo::* )(ptr *),
_Ty=ptr *,
_Secure_validation=true,
_InIt=std::list<ptr *>::_Iterator<true>
]

thanks

well i think i may have discovered the solution myself hehe

for_each(myList.begin(), myList.end(), std::bind1st(std::mem_fun(&Foo::memFunc), this));

seems to be working
