DRMSetGlobalOptions 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 DRMSetGlobalOptions function sets the transport protocol to a specified value and optionally specifies whether the server lockbox is used.
DRMEXPORT HRESULT UDAPICALL DRMSetGlobalOptions( [in] DRMGLOBALOPTIONS eGlobalOptions, [in] LPVOID pvdata, [in] DWORD dwlen );
A value of the DRMGLOBALOPTIONS enumeration that specifies the option to set.
Only one option can be specified in each call to DRMSetGlobalOptions. For example, if both WinHTTP and the server lockbox are required, you must call DRMSetGlobalOptions twice, once with eGlobalOptions set to DRMGLOBALOPTIONS_USE_WINHTTP and once with eGlobalOptions set to DRMGLOBALOPTIONS_USE_SERVERSECURITYPROCESSOR.
A pointer to a void value. This parameter is not currently used.
The size, in bytes, of the pvdata buffer. This parameter is not currently used.
If the function succeeds, the function returns S_OK.
If the function fails, it returns an HRESULT value that indicates the error. Possible values include, but are not limited to, those in the following list. For a list of common error codes, see Common HRESULT Values.
Applications cannot toggle between the WinHTTP and WinINet protocols.
WinINet does not support usage under the network service account. If an application will be run under the network service account, the application must specify the DRMGLOBALOPTIONS_USE_WINHTTP option.
An AD RMS-enabled server application should call the DRMSetGlobalOptions function prior to calling any other rights management functions. Calling DRMSetGlobalOptions after other rights management functions have been called will not change the type of lockbox or transport protocol in use.
