Description:

    This file contains the RASADMIN structures, defines and
    function prototypes for the following APIs and they can
    be imported from RASSAPI.DLL:

     RasAdminServerGetInfo
     RasAdminGetUserAccountServer
     RasAdminUserSetInfo
     RasAdminUserGetInfo
     RasAdminPortEnum
     RasAdminPortGetInfo
     RasAdminPortClearStatistics
     RasAdminPortDisconnect
     RasAdminFreeBuffer

Note:

    This header file and the sources containing the APIs will work
    only with UNICODE strings.
