Return dynamically allocated memory from C++ to C

Question

I have a dll that must be useable from C etc, so I cant use string objects etc as a normal would, but I\'m not sure on how to do this safely..

const char *Ge         


        

Answer 1

Well obviously anytime you are returning pointers to memory allocated inside a function the deallocating must come externally, unless you are using garbage collection. If you don't want to do this, allocate a character buffer b efore calling GetString() and change the prototype to

int get_string(const char* buffer);

Then fill up the buffer. But returning a point to malloced data is fine.
