RAS WinAPI的MSDN说明RasDial
The RasDial function establishes a RAS connection between a RAS client and a RAS server. The connection data includes callback and user-authentication information.
DWORD RasDial(
LPRASDIALEXTENSIONS lpRasDialExtensions,
// pointer to function extensions data
LPCTSTR lpszPhonebook, // pointer to full path and file
// name of phone-book file
LPRASDIALPARAMS lpRasDialParams,
// pointer to calling parameters data
DWORD dwNotifierType, // specifies type of RasDial event handler
LPVOID lpvNotifier, // specifies a handler for RasDial events
LPHRASCONN lphRasConn // pointer to variable to receive
// connection handle
);
Parameters
lpRasDialExtensions
[in] Windows NT/2000/XP: Pointer to a RASDIALEXTENSIONS structure that specifies a set of RasDial extended features to enable. Set this parameter to NULL if there is not a need to enable these features.
Windows 95/98/Me: This parameter is ignored. On these platforms, RasDial always uses the default behaviors for the RASDIALEXTENSIONS options.
lpszPhonebook
[in] Windows NT/2000/XP: Pointer to a null-terminated string that specifies the full path and file name of a phone-book (PBK) file. If this parameter is NULL, the function uses the current default phone-book file. The default phone-book file is the one selected by the user in the User Preferences property sheet of the Dial-Up Networking dialog box.
Windows 95: This parameter should always be NULL. Dial-up networking stores phone-book entries in the registry rather than in a phone-book file.
lpRasDialParams
[in] Pointer to a RASDIALPARAMS structure that specifies calling parameters for the RAS connection.
The caller must set the RASDIALPARAMS structure's dwSize member to sizeof(RASDIALPARAMS) to identify the version of the structure being passed.
dwNotifierType
[in] Specifies the nature of the lpvNotifier parameter. If lpvNotifier is NULL, dwNotifierType is ignored. If lpvNotifier is not NULL, set dwNotifierType to one of the following values. Value Meaning
0xFFFFFFFF The lpvNotifier parameter is a handle to a window to receive progress notification messages. In a progress notification message, wParam is the equivalent of the rasconnstate parameter of RasDialFunc and RasDialFunc1, and lParam is the equivalent of the dwError parameter of RasDialFunc and RasDialFunc1.
The progress notification message uses a system registered message code. You can obtain the value of this message code as
