Allocates a new MSRingPlayer object.
name : | The path to the 16-bit 8khz raw file to be played as a ring. |
seconds : | The number of seconds that separates two rings. |
| Returns : | a pointer the the object, NULL if name could not be open. |
void ms_ring_player_destroy (MSRingPlayer *obj);
Destroy a MSRingPlayer object.
obj : | A valid MSRingPlayer object. |
