static character pointer within a function

Hi All,

I am not sure all static variables define locally within a function is putting on stack memory or on the heap or global memory space.
Does anyone know?
Thanks!

Code:

---

class Foo
{
  public:
  Foo();
  void convert_message_to_string()
  {
      static char * strbuffer;    // is strbuffer on stack or heap after function return???
    // convert an unpredict size of message struct into string, then return . With restriction of not allow using New operator or Malloc(). Gosh! 
  }

  private:
  struct MessageType message;

};

All static variables are located in the program's data segment where other globals reside.

Note that the variable is just an uninitialized pointer. What it points to depends on what you assign to it. If you use new to allocate space for the buffer, then that space resides on the heap. If you assign the address of an existing variable or literal then the pointer might point to memory somewhere else.

Isn't it implicitily initialized to a null pointer because it has static storage duration?

I'm not sure. You are probably right.
