  WMT_DRMLA_TAMPERED 

};

Constants

WMT_DRMLA_TRUSTED

Indicates that the license acquisition URL is the original one provided with the content.

WMT_DRMLA_TAMPERED

Indicates that the license acquisition URL was originally signed and has been tampered with.

Remarks

When a WMT_LICENSEURL_SIGNATURE_STATE message is received in the OnStatus callback method, pValue will be set to one of the WMT_DRMLA_TRUST constants, which indicate whether there is any problem with the digital signature applied to the license acquisition URL.
