IWMDeviceRegistration::RegisterDevice method (wmsdkidl.h)
[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
[RegisterDevice is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. Instead, use Microsoft PlayReady. ]
The RegisterDevice method adds a device to the device list.
Syntax
HRESULT RegisterDevice(
[in] DWORD dwRegisterType,
[in] BYTE *pbCertificate,
[in] DWORD cbCertificate,
[in] DRM_VAL16 SerialNumber,
[out] IWMRegisteredDevice **ppDevice
);
Parameters
[in] dwRegisterType
The type of the device to register. Devices that support Windows Media DRM 10 for Network Devices use DRM_DEVICE_REGISTER_TYPE_STREAMING. To register a device that does not use Windows Media DRM 10 for Network Devices, set this parameter to 0.
[in] pbCertificate
Address of the device certificate in memory.
[in] cbCertificate
The size of the certificate data in bytes.
[in] SerialNumber
128-bit device identifier, stored in a DRM_VAL16 structure.
[out] ppDevice
Address of a variable that receives a pointer to the IWMRegisteredDevice interface of the newly registered device.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
The pbCertificate parameter is NULL, but the cbCertificate parameter is greater than zero.
OR The dwRegisterType parameter is set to DRM_DEVICE_REGISTER_TYPE_STREAMING, but no certificate is provided. |
|
The method could not allocate memory for an internal variable. |
Remarks
Registration is triggered by a registration request message sent to your application by the device. When you receive this message, you must first extract the certificate and device identifier from it by calling IWMDRMMessageParser::ParseRegistrationReqMsg. After parsing the message, pass the certificate and device identifier to this method.
After you register a device, you must perform proximity detection before sending any protected media data to it.
The DRM_DEVICE_REGISTER_TYPE_STORAGE register type is defined, but is not used in this release.
