SoundInit() just verifies that a wave driver is loaded.
|
|
HeartsPlaySound() plays the sound given a resource id.

Plays the specified sound from the resource file.

The static variable hRes is used as a flag to know if memory has been

allocated and locked for the sound. If hRes is non-zero, a sound is

still playing, or at least the memory for the sound has not been unlocked
|
|
and freed. The application must call HeartsPlaySound(NULL, 0) to free this

memory before exiting. (The game destructor does this. It also

|
happens at the end of each hand.)
