Function Overloading for the standard library functions in C++

Question

I have a free function as part of a class. In the constructor for the class i am doing some malloc operations . So in the destructor i am trying to free that memory. But VS10 compiler complains that the

free(pointer); 

doesn't match the signature of the free function of my class.

So question is In a class wherein if we have implemented methods which have same names as that of standard library functions . How to call one over the other.

Regards,

You have to use the scope operator to get the correct scope of the free function:

::free(pointer);

Having :: at the beginning tells the compiler to look for the free function at the global scope, not the closest scope which is your class.
