Hi.
I''ve been trying to use a function pointer into a C++ class (pointing to member functions from that class), but I can''t make it work...
the only way I''ve found to make it work is declareting the member functions wich I''ll be pointing to as "static":
#include <iostream>
class player_t{
public:
player_t();
void (*exec)( void );
static void my_function( );
};
player_t:
layer_t(){
exec = my_function;
}
void player_t::my_function( ){
cout << "hi, I''m my_function();" << endl;
}
int main( void ){
jugador_t J;
J.exec();
return 0;
}
But doing so those functions will lack of the implicit "this" pointer passed in all member functions. So I''ll have to pass them on an explicit way:
#include <iostream>
class player_t{
public:
player_t();
void (*exec)( player_t * );
static void my_function( player_t * );
};
player_t:layer_t(){
exec = my_function;
}
void player_t::my_function( player_t *THIS ){
cout << "hi, I''m my_function();" << endl;
}
int main( void ){
jugador_t J;
J.exec( &J );
return 0;
}
How ever, I''m trying to find a way to use function pointers without having to declare them as "static", so I can keep my code clean without any wierd parameters...
ANY IDEA??????????????
