ISCPSecureQuery3::GetRightsOnClearChannel method (mswmdm.h)

The GetRightsOnClearChannel method retrieves rights information for the current piece of content on a clear channel.

Syntax

HRESULT GetRightsOnClearChannel(
  [in]  BYTE                *pData,
  [in]  DWORD               dwSize,
  [in]  BYTE                *pbSPSessionKey,
  [in]  DWORD               dwSessionKeyLen,
  [in]  IMDSPStorageGlobals *pStgGlobals,
  [in]  IWMDMProgress3      *pProgressCallback,
  [out] PWMDMRIGHTS         *ppRights,
  [out] UINT                *pnRightsCount
);

Parameters

[in] pData

Pointer to data object.

[in] dwSize

Number of bytes of data in the pData buffer.

[in] pbSPSessionKey

Pointer to an array of bytes containing the session key for securing communication with the service provider to which pStgGlobals points.

[in] dwSessionKeyLen

Length of the byte array to which pbSPSessionKey points.

[in] pStgGlobals

Pointer to an IWMDMStorageGlobals interface on the root storage of the media or device to or from which the file is being transferred.

[in] pProgressCallback

Pointer to an IWMDMProgress3 interface.

[out] ppRights

Pointer to an array of WMDMRIGHTS structures containing the rights information for this object. The array is allocated by this method and must be freed using CoTaskMemFree.

[out] pnRightsCount

Number of WMDMRIGHTS structures in the ppRights array.

Return value

If the method succeeds, it returns S_OK. If the method fails, it returns an HRESULT error code.

Return code	Description
WMDM_E_CALL_OUT_OF_SEQUENCE	This method was called out of sequence. ISCPSecureQuery::GetDataDemands and then ISCPSecureQuery::ExamineData must be called, in that order.
WMDM_E_MAC_CHECK_FAILED	The message authentication code is not valid.
WMDM_E_NORIGHTS	The caller does not have the rights required to perform the requested operation.
E_INVALIDARG	A parameter is invalid or is a NULL pointer.
E_FAIL	An unspecified error occurred.

Remarks

This method is identical to ISCPSecureQuery::GetRights except that the parameters passed to this method are not encrypted. Consequently this method is more efficient.
