Function Name = LeapDesktopAppFull::volumeManipulation
Descriptive Name = Increase/decrease/mute/unmute the volume
Function =
This functions is responsible for performing the actions of increasing/
decreasing/muting/unmuting the volume. Makes use of the available functions on
windows to construct and initialize the interface of audio devices for communication.
Dependencies =
None
Restrictions =
Must have audio devices connected, running and capable of being accessed through the
IMMDeviceEnumerator interface.
Input =
string controlOption - The volume action to be performed, supports the following options:
VOLUME_STEP_UP - This option will increase the volume by 1
VOLUME_STEP_DOWN - This option will decrease the volume by 1
VOLUME_MUTE_UNMUTE - This option will mute or unmute based on
what the state of the volume currently is.
Output =
Currently there are no outputs from this functions as it only performs the action.
Future TODO is to make sure errors are handled and appropriate response is returned.
