DRMDuplicateSession function (msdrm.h)

[The AD RMS SDK leveraging functionality exposed by

the client in Msdrm.dll is available for use in Windows Server 2008, Windows Vista, Windows Server 2008 R2, Windows 7, Windows Server 2012, and Windows 8. It may be altered or

unavailable in subsequent versions. Instead, use Active Directory Rights Management Services SDK 2.1,

which leverages functionality exposed by the client in Msipc.dll.]

The DRMDuplicateSession function duplicates a client or license storage session.

Syntax

DRMEXPORT HRESULT UDAPICALL DRMDuplicateSession(
  [in]  DRMHSESSION hSessionIn,
  [out] DRMHSESSION *phSessionOut
);

Parameters

[in] hSessionIn

A handle to a session to duplicate.

[out] phSessionOut

Pointer to the duplicated session handle. Call DRMCloseSession to close the handle.

Return value

If the function succeeds, the function returns S_OK.

If the function fails, it returns an HRESULT value that indicates the error. For a list of common error codes, see Common HRESULT Values.

Remarks

Creating, copying, and closing handles with the appropriate function allows the rights management system to maintain a reference count on resources and free them appropriately, and also clears sensitive data from memory. Call DRMCloseSession to close the handle created by calling this function.
