For further details about callback delegates see the How to synchronize the container application with the API tutorial.
Further information about management of casting sessions can be found inside the How to use the control as a source for streaming servers like SHOUTcast tutorial.

Syntax
[Visual Basic] Public Function CallbackForCastingEventsSet ( function as CallbackForCastingEvents ) as enumErrorCodes |
[C#] public enumErrorCodes CallbackForCastingEventsSet ( CallbackForCastingEvents function ); |
[C++] public: enumErrorCodes CallbackForCastingEventsSet ( CallbackForCastingEvents function ); |
Parameter |
Description |
|
|
function |
Callback function that will receive events generated by the casting manager. 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 CallbackForCastingEventsSetPtr ( (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 |

Negative value |
An error occurred (see the LastError property for further error details) |
enumErrorCodes.NOERROR (0) |
