FAQ
| Q: |
How is this different from the Win32 WaitForSingleObject()
function? |
| A: |
It's only different in the values it returns. This
function is used to abstract any dependencies on the Win32 platform to
help ensure future portability. |
Example
#include <iostream.h>
#include "SparkModel.h"
// get values
while (1)
{
if (model.wait(enemy_dist_event, 0))
{
cout << "Enemy distance value changed. ";
cout << "Current value is: ";
cout
<< model.get_value(ENEMY_DISTANCE) << endl;
}
} // end forever loop
return 0;
} // end main()
