Previous pageReturn to chapter overviewNext page

Remarks

 

Obtains the current speed of the CD drive. The speed can be modified through the CdDriveSpeedSet method.

 

 

Syntax

 

[Visual Basic]

control.CdDriveMaxSpeedGet (

nCdDriveIndex as integer,

nMaxSpeed as long

) as enumErrorCodes


 

[C++]

short control.CdDriveMaxSpeedGet (

short CdDriveSpeedGet,

long *nMaxSpeed

);


 

 

Parameter

Description

 

 

nCdDriveIndex

Number representing the zero-based index of the involved CD drive.

Installed CD drives can be enumerated using the GetCdDrivesCount method and their friendly description can be retrieved through the GetCdDriveDesc method.

nMaxSpeed

Reference that, after returning from the method call, will contain the maximum speed supported by the CD drive expressed in Kbytes per second.

You can divide the speed by 176.4 to get the real-time speed multiplier; if for example the returned values should be 7096, the operation to perform would be

7096 / 176.4 = "40x".
