RasGetProjectionInfo (Windows Embedded CE 6.0)

1/6/2010

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

Syntax

DWORD RasGetProjectionInfo(
  HRASCONN hrasconn, 
  RASPROJECTION rasprojection, 
  LPVOID lpprojection, 
  LPDWORD lpcb 
);

Remarks

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

• rasprojection
  [in] A RASPROJECTION enumerated type value that specifies the protocol of interest.

• lpprojection
  [out] Long pointer 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	Definition
  RASP_PppIp	RASPPPIP	Specifies the IP control protocol. IPCP is a PPP network control protocol used to negotiate the parameters necessary to ship IP packets on a WAN link.

• lpcb
  [in, out] Long pointer 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 Value

Zero indicates success. A nonzero error value indicates failure. The function may return a nonzero RAS error code, or one of the following error codes.

Value	Description
ERROR_BUFFER_TOO_SMALL	The buffer pointed to by lpprojection is not large enough to contain the requested information.
ERROR_INVALID_HANDLE	The hrasconn parameter is not a valid handle.
ERROR_INVALID_PARAMETER	One of the parameters is invalid.
ERROR_PROTOCOL_NOT_CONFIGURED	The control protocol for which information was requested neither succeeded nor failed, because the connection's phone-book entry did not require that an attempt to negotiate the protocol be made. This is a RAS error code.

Remarks

The remote access projection process negotiates network protocol-specific information between a remote access server and a remote client. A remote access server uses this network protocol-specific information to represent a remote client on the network.

Requirements

Header	ras.h
Library	coredll.lib
Windows Embedded CE	Windows CE 3.0 and later
