You should most properly use a plain function with C linkage as the
callback. If you want to access instance (non-static) data you need to
pass in an instance pointer; and if it needs to access private data it
should be made a friend.
Basically what you want is something like this:
// *** header file ***
extern "C" gboolean cframe_read_data(void* data);
class CFrame {
...
public:
...
gboolean ReadData();
};
// *** implementation file ***
gboolean cframe_read_data(void* data) {
return static_cast<CFrame*>(data)->ReadData();
}
int main() {
...
CFrame* cf = new CFrame;
g_timer_add_seconds( 1, cframe_read_data, cf);
...
}
This is all very basic C/C++
