PDDocGetPermissions() has been deprecated since 5.0 and says to use PDDocPermRequest()
I have used PDDocPermRequest() to determine PDPermReqOprModify, but doesn't tell me pdPermEdit or pdPermEditNotes.
I am looking for all three of those values as http://help.adobe.com/livedocs/acrobat_sdk/11/Acrobat11_HTMLHelp/Plugins_Security.45.6.htm l states "To be allowed to save a file, the user must have PDPermReqOprModify or either pdPermEdit or pdPermEditNotes permission".
