1/6/2010

This function is used to configure a Windows Embedded CE–based device to function as a Remote Access Service (RAS) server.

Syntax

RasIOControl IMPLICIT_DECL(
  LPVOID hRasConn,
  DWORD dwCode,
  PBYTE pBufIn,
  DWORD dwLenIn,
  PBYTE pBufOut,
  DWORD dwLenOut,
  PDWORD pdwActualOut
);

Parameters

• hRasConn
  [in] Set this parameter to NULL for configuring RAS server parameters.

• dwCode
  [in] I/O control code describing which operation is performed.

  The following table shows a list of possible values for dwCode.

  Value	Description	BufInType	BufOutType

  RASCNTL_SERVER_ENABLE	Turns the PPP server on.	NULL	NULL
  RASCNTL_SERVER_DISABLE	Turns the PPP server off.	NULL	NULL
  RASCNTL_SERVER_GET_PARAMETERS	Obtains the global server parameters.	NULL	RASCNTL_SERVERSTATUS
  RASCNTL_SERVER_SET_PARAMETERS	Sets the global server parameters.	RASCNTL_SERVERSTATUS	NULL
  RASCNTL_SERVER_LINE_ADD	Adds a line to be managed by the PPP server.	RASCNTL_SERVERLINE	NULL
  RASCNTL_SERVER_LINE_REMOVE	Removes a line being managed by the PPP server.	RASCNTL_SERVERLINE	NULL
  RASCNTL_SERVER_LINE_ENABLE	Enables management of a line.	RASCNTL_SERVERLINE	NULL
  RASCNTL_SERVER_LINE_DISABLE	Disables management of a line.	RASCNTL_SERVERLINE	NULL
  RASCNTL_SERVER_LINE_GET_PARAMETERS	Obtains parameters of a line.	RASCNTL_SERVERLINE	RASCNTL_SERVERLINE
  RASCNTL_SERVER_LINE_SET_PARAMETERS	Sets parameters of a line.	RASCNTL_SERVERLINE	NULL
  RASCNTL_SERVER_USER_SET_CREDENTIALS	Allows a user name or password.	RASCNTL_SERVERUSERCREDENTIALS	NULL
  RASCNTL_SERVER_USER_DELETE_CREDENTIALS	Removes a user name or password.	RASCNTL_SERVERUSERCREDENTIALS	NULL
  RASCNTL_SERVER_LINE_GET_CONNECTION_INFO	Obtains state information for a server line.	RASCNTL_SERVERLINE	RASCNTL_SERVERCONNECTION
  RASCNTL_SERVER_GET_IPV6_NET_PREFIX	Obtains the IPv6 network prefix pool.	NULL	RASCNTL_SERVER_IPV6_NET_PREFIX
  RASCNTL_SERVER_SET_IPV6_NET_PREFIX	Sets the IPv6 network prefix pool.	RASCNTL_SERVER_IPV6_NET_PREFIX	NULL

• pBufIn
  [in] I/O control code-dependent input buffer used to pass information to configure server parameters.

• dwLenIn
  [in] Size of pBufIn in bytes.

• pBufOut
  [out] I/O control code-dependent output buffer in which server information is returned.

• dwLenOut
  [in] Size of pBufOut in bytes.

• pdwActualOut
  [out] Contains the number of bytes of information that were written into pBufOut.

Return Value

This function returns SUCCESS if the function call succeeded or an error code if an error occurred. If the output buffer is too small for the data to be returned, the function will return an ERROR_BUFFER_TOO_SMALL status code.
