Syntax

 

[Visual Basic]

Public Function CallbackForCdDrivesEventsSet (

function as CallbackForCdDrivesEvents

) as enumErrorCodes


 

[C#]

public enumErrorCodes CallbackForCdDrivesEventsSet (

CallbackForCdDrivesEvents function

);


 

[C++]

public: enumErrorCodes CallbackForCdDrivesEventsSet (

CallbackForCdDrivesEvents function

);


 

 

Parameter

Description

 

 

function

Pointer to the callback function that will receive CD drives 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 CallbackForCdDrivesEventsSetPtr (

(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. Check the LastError property value in order to see the last error.

enumErrorCodes.ERR_NOERROR (0)

The method call was successful.
