RasGetProjectionInfo info  Overview  Group

The RasGetProjectionInfo function obtains information about a remote access projection operation for a specified remote access component protocol.

DWORD RasGetProjectionInfo(

Parameters

hrasconn

Handle to the remote access connection of interest. An application obtains a RAS connection handle from the RasDial or RasEnumConnections function.

rasprojection

A RASPROJECTION enumerated type value that specifies the protocol of interest.

lpprojection

Points to a buffer that will receive the information specified by the rasprojection parameter. The information will be in a structure appropriate to the rasprojection value:

rasprojection value	Data structure
RASP_Amb	RASAMB
RASP_PppNbf	RASPPPNBF
RASP_PppIpx	RASPPPIPX
RASP_PppIp	RASPPPIP

lpcb

Points to a variable that, on entry, specifies the size in bytes of the buffer pointed to by lpprojection. On exit, this variable contains the size of buffer needed to contain the specified projection information.

Return Values

If the function succeeds, the return value is zero.

If the function fails, the return value is an error code. The function may return a nonzero RAS error code, or one of the following error codes:

Remarks

Remote access projection is the process whereby a remote access server and a remote client negotiate network protocol-specific information. A remote access server uses this network protocol-specific information to represent a remote client on the network.

Windows NT: Remote access projection information is not available until the operating system has executed the RasDial RASCS_Projected state on the remote access connection. If RasGetProjectionInfo is called prior to the RASCS_Projected state, it returns ERROR_PROJECTION_NOT_COMPLETE.

Windows 95: Windows 95 Dial-Up Networking does not support the RASCS_Projected state. The projection phase may be done during the RASCS_Authenticate state. If the authentication is successful, the connection operation proceeds to the RASCS_Authenticated state, and projection information is available for successfully configured protocols. If RasGetProjectionInfo is called prior to the RASCS_Authenticated state, it returns ERROR_PROTOCOL_NOT_CONFIGURED.
