The PPP_LCP_INFO structure contains information that describes the results of a PPP Link Control Protocol (LCP) negotiation.

Syntax

typedef struct _PPP_LCP_INFO {
  DWORD dwError;
  DWORD dwAuthenticationProtocol;
  DWORD dwAuthenticationData;
  DWORD dwRemoteAuthenticationProtocol;
  DWORD dwRemoteAuthenticationData;
  DWORD dwTerminateReason;
  DWORD dwRemoteTerminateReason;
  DWORD dwOptions;
  DWORD dwRemoteOptions;
  DWORD dwEapTypeId;
  DWORD dwRemoteEapTypeId;
} PPP_LCP_INFO;

Members

dwError

Specifies the error that occurred if the negotiation was unsuccessful.

dwAuthenticationProtocol

Specifies the authentication protocol used to authenticate the local computer. This member can be one of the following values.

Value Meaning
PPP_LCP_PAP
 Password Authentication Protocol
PPP_LCP_SPAP
 Shiva Password Authentication Protocol
PPP_LCP_CHAP
 Challenge Handshake Authentication Protocol
PPP_LCP_EAP
 Extensible Authentication Protocol

dwAuthenticationData

Specifies additional information about the authentication protocol specified by the dwAuthenticationProtocol member. This member can be one of the following values.

Value Meaning
PPP_LCP_CHAP_MD5
 MD5 CHAP
PPP_LCP_CHAP_MS
 Microsoft CHAP
PPP_LCP_CHAP_MSV2
 Microsoft CHAP version 2

dwRemoteAuthenticationProtocol

Specifies the authentication protocol used to authenticate the remote computer. See the dwAuthenticationProtocol member for a list of possible values.

dwRemoteAuthenticationData

Specifies additional information about the authentication protocol specified by dwRemoteAuthenticationProtocol. See the dwAuthenticationData member for a list of possible values.

dwTerminateReason

Specifies the reason the connection was terminated by the local computer. This member always has a value of zero.

dwRemoteTerminateReason

Specifies the reason the connection was terminated by the remote computer. This member always has a value of zero.

dwOptions

Specifies information about LCP options in use by the local computer. This member is a combination of the following flags.

Flag Meaning
PPP_LCP_MULTILINK_FRAMING
 The connection is using multilink
RASLCPO_PFC
 Protocol Field Compression (see RFC 1172)
RASLCPO_ACFC
 Address and Control Field Compression (see RFC 1172)
RASLCPO_SSHF
 Short Sequence Number Header Format (see RFC 1990)
RASLCPO_DES_56
 DES 56-bit encryption
RASLCPO_3_DES
 Triple DES Encryption

dwRemoteOptions

Specifies information about LCP options in use by the remote computer. This member is a combination of the following flags.

Flag Meaning
PPP_LCP_MULTILINK_FRAMING
 The connection is using multilink.
RASLCPO_PFC
 Protocol Field Compression (see RFC 1172)
RASLCPO_ACFC

RASLCPO_DES_56
 DES 56-bit encryption
RASLCPO_3_DES
 Triple DES Encryption

dwEapTypeId

Specifies the type identifier of the Extensible Authentication Protocol (EAP) used to authenticate the local computer. The value of this member is valid only if dwAuthenticationProtocol is PPP_LCP_EAP.

dwRemoteEapTypeId

Specifies the type identifier of the Extensible Authentication Protocol (EAP) used to authenticate the remote computer. The value of this member is valid only if dwRemoteAuthenticationProtocol is PPP_LCP_EAP.
