RASPROJECTION

The RASPROJECTION enumeration type defines values that specify a particular authentication protocol or Point-to-Point Protocol (PPP) control protocol. An application passes a value of this type to the RasGetProjectionInfo function to specify the protocol of interest.

typedef enum _RASPROJECTION { 
  RASP_Amb = 0x10000, 
  RASP_PppNbf = 0x803F, 
  RASP_PppIpx = 0x802B, 
  RASP_PppIp = 0x8021 
  RASP_PppCcp = 0x80FD;
  RASP_PppLcp = 0xC021;
  RASP_Slip = 0x20000
} RASPROJECTION ; 

Each of the RASPROJECTION enumerators has a corresponding data structure; the RasGetProjectionInfo function returns the specified information in a structure of that type.

Enumerator Value Meaning
RASP_Amb Specifies the Authentication Message Block (AMB) authentication protocol. AMB is a NetBIOS-based protocol used to authenticate with downlevel remote access servers ( all those prior to Windows NT 3.5). The corresponding data structure is a RASAMB.
RASP_PppNbf Specifies the NetBEUI Framer (NBF) protocol. NBFCP is a PPP network control protocol used to negotiate the parameters necessary to ship NetBEUI packets on a WAN link. The corresponding data structure is a RASPPPNBF.
RASP_PppIpx Specifies the Internetwork Packet Exchange (IPX) control protocol. IPXCP is a PPP network control protocol used to negotiate the parameters necessary to ship IPX packets on a WAN link. The corresponding data structure is a RASPPPIPX.
RASP_PppIp Specifies the Internet Protocol (IP) control protocol. IPCP is a PPP network control protocol used to negotiate the parameters necessary to ship IP packets on a WAN link. The corresponding data structure is a RASPPPIP.
RASP_PppCcp Specifies the Compression Control Protocol (CCP). CCP enables computers using PPP to negotiate compression algorithms and parameters. The corresponding data structure is RASPPPCCP.
RASP_PppLcp Specifies the Link Control Protocol (LCP). LCP is used by computers to establish, modify, and terminate PPP connections. The corresponding data structure is RASPPPLCP.
RASP_Slip Specifies the Serial Line Internet Protocol (SLIP). SLIP is a framing protocol used primarily in UNIX environments.
