RasGetAutodialParam info  Overview  Group

The RasGetAutodialParam function retrieves the value of an AutoDial parameter.

DWORD RasGetAutodialParam(

DWORD dwKey,	// indicates the parameter to retrieve
LPVOID lpvValue,	// pointer to a buffer that receives the value
LPDWORD lpdwcbValue	// size, in bytes, of the buffer
);

Parameters

dwKey

Indicates the AutoDial parameter to retrieve. This parameter can be one of the following values.

Value	Meaning
RASADP_DisableConnectionQuery	The lpvValue parameter returns a DWORD value. If this value is zero (the default), AutoDial displays a dialog box to query the user before creating a connection. If this value is 1, and the AutoDial database has the phone-book entry to dial, AutoDial creates a connection without displaying the dialog box.
RASADP_LoginSessionDisable	The lpvValue parameter returns a DWORD value. If this value is 1, the system disables all AutoDial connections for the current logon session. If this value is zero (the default), AutoDial connections are enabled. The AutoDial system service changes this value to zero when a new user logs on to the workstation.
RASADP_SavedAddressesLimit	The lpvValue parameter returns a DWORD value that indicates the maximum number of addresses that AutoDial stores in the registry. AutoDial first stores addresses that it used to create an AutoDial connection; then it stores addresses that it learned after a RAS connection was created. Addresses written using the RasSetAutodialAddress function are always saved, and are not included in calculating the limit. The default value is 100.
RASADP_FailedConnectionTimeout	The lpvValue parameter returns a DWORD value that indicates a timeout value, in seconds. When an AutoDial connection attempt fails, the AutoDial system service disables subsequent attempts to reach the same address for the timeout period. This prevents AutoDial from displaying multiple connection dialog boxes for the same logical request by an application. The default value is 5.

lpvValue

Pointer to a buffer that receives the value for the specified parameter.

lpdwcbValue

Pointer to a DWORD value. On input, set this value to indicate the size, in bytes, of the lpvValue buffer. On output, this value indicates the actual size of the value written to the buffer.

Return Values

If the function succeeds, the return value is zero.

If the function fails, the return value can be one of the following error codes.

Value	Meaning
ERROR_INVALID_PARAMETER	The dwKey or lpvValue parameter is invalid.
ERROR_INVALID_SIZE	The size specified by the lpdwcbValue is too small.
