Syntax
[Visual Basic] Public Function CallbackForRecorderEventsSet ( function as CallbackForRecorderEvents ) as enumErrorCodes |
[C#] public enumErrorCodes CallbackForRecorderEventsSet ( CallbackForRecorderEvents function ); |
[C++] public: enumErrorCodes CallbackForRecorderEventsSet ( CallbackForRecorderEvents function ); |
Parameter |
Description |
|
|
function |
Pointer to the callback function that will receive CoreAudio devices related events. Remember that callback functions must be as fast as possible in order to avoid slowing down overall performances. |
when using the API from Unmanaged C++ through COM interaction, where the client application is totally unaware about .NET delegates, you should use the "Ptr" version of the method which allows passing the pointer to the callback function:
[Unmanaged C++] enumErrorCodes CallbackForRecorderEventsSetPtr ( (UINT_PTR) functionPointer ); |
Parameter |
Description |
|
|
functionPointer |
Pointer to the callback function. See the Adding the API to an unmanaged Visual C++ project tutorial for details about usage of the "Ptr" version of these methods. |
Return value
Value |
Meaning |

enumErrorCodes.ERR_NOERROR (0) |
