Compiler returns error if we calling from static function non-static function. Following example solving this problem.
We create simple class, which contains static function, non static function and static void pointer to some object.
class CClass
{
static void *ms_pObject; ///< Void pointer to some object
void NonStaticFunction();
public:
CClass ();
~CClass();
static void StaticFunction();
};
Declare static pointer to some object in source file.
void *CClass::ms_pObject; ///< Void pointer to some object
Now in static function cast the void pointer to the class CClass and call by this class non-static function.
void CClass::StaticFunction()
{
std::cout << "I try call non static function from static function..." << endl;
// Cast the void pointer
CClass *pSomeClass = (CClass*)ms_pObject;
// Try call non static function
pSomeClass->NonStaticFunction();
}
void CClass::NonStaticFunction()
{
std::cout << "Ok... Non static function now calling from static function ..." << endl;
}
