RasSetAutodialAddress info  Overview  Group

The RasSetAutodialAddress function can add an address to the AutoDial mapping database. Alternatively, the function can delete or modify the data associated with an existing address in the database.

DWORD RasSetAutodialAddress(

LPTSTR lpszAddress,	// pointer to a network address string
DWORD dwReserved,	// reserved; must be zero
LPRASAUTODIALENTRY lpAutoDialEntries,	// pointer to buffer containing AutoDial entry data
DWORD dwcbAutoDialEntries,	// size, in bytes, of the buffer
DWORD dwcAutoDialEntries	// number of entries in the buffer
);

Parameters

lpszAddress

Pointer to a null-terminated string that specifies the address to add, delete, or modify. This can be an IP address (“127.95.1.4”), Internet host name (“www.microsoft.com”), or NetBIOS name (“products1”).

dwReserved

Reserved; must be zero.

lpAutoDialEntries

Pointer to an array of one or more RASAUTODIALENTRY structures to be associated with the lpszAddress address. If lpAutoDialEntries is NULL and dwcbAutodialEntries is zero, RasSetAutodialAddress deletes all structures associated with lpszAddress from the mapping database.

dwcbAutoDialEntries

Specifies the size, in bytes, of the lpAutodialEntries buffer.

dwcAutoDialEntries

Specifies the number of RASAUTODIALENTRY structures in the lpAutoDialEntries buffer.

Return Values

If the function succeeds, the return value is zero.

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

Value	Meaning
ERROR_INVALID_SIZE	The dwSize member of the RASAUTODIALENTRY structure is an invalid value.
ERROR_INVALID_PARAMETER	The lpszAddress parameter was NULL.

Remarks

An address in the AutoDial mapping database can have any number of associated RASAUTODIALENTRY entries. Each entry specifies AutoDial information for a particular TAPI dialing location.

If the address specified by the lpszAddress parameter is an existing address in the database and the lpAutoDialEntries parameter is not NULL, the RasSetAutodialAddress function modifies the set of AutoDial entries associated with the address. If an entry in the lpAutoDialEntries array specifies a dialing location for which the address already has an entry, the function replaces the existing entry with the new entry. Otherwise, the function simply adds the lpAutoDialEntries entries to the set of entries for the address.

If the lpszAddress address exists in the database and lpAutoDialEntries is NULL and dwcbAutodialEntries is zero, RasSetAutodialAddress deletes the address from the database.

If the lpszAddress address does not exist in the database, RasSetAutodialAddress adds the address to the database. The lpAutoDialEntries parameter specifies the AutoDial entries to associate with the new address.
