RasSetCredentials

[New - Windows NT]

The RasSetCredentials function sets the user credentials associated with a specified RAS phone-book entry.

DWORD RasSetCredentials(

LPTSTR lpszPhonebook,	// pointer to the full path and filename of a phone-book file
LPTSTR lpszEntry,	// pointer to the name of a phone-book entry
LPRASCREDENTIALS lpCredentials	// pointer to structure that specifies the credentials
);

Parameters

lpszPhonebook

Pointer to a null-terminated string that specifies the full path and filename 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.

lpszEntry

Pointer to a null-terminated string that contains the name of a phone-book entry.

lpCredentials

Pointer to a RASCREDENTIALS structure that specifies the user credentials to set for the specified phone-book entry. Before calling RasSetCredentials, set the dwSize member of the structure to sizeof(RASCREDENTIALS). Set the dwMask member to indicate the credential information to be set.

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_CANNOT_OPEN_PHONEBOOK	The specified phone book cannot be found.
ERROR_CANNOT_FIND_PHONEBOOK_ENTRY	The specified entry does not exist in the phone book.
ERROR_INVALID_PARAMETER	The lpCredentials parameter was NULL.
ERROR_INVALID_SIZE	The dwSize member of the RASCREDENTIALS structure is an unrecognized value.

Remarks

The RasSetCredentials function sets the user credentials associated with a specified RAS phone-book entry. The credentials stored with a phone-book entry are the credentials of the last user to successfully connect using the specified phone-book entry, or the credentials subsequently specified in a call to the RasSetCredentials or RasSetEntryDialParams function for the phone-book entry.

The RasSetCredentials function is the preferred way of securely storing credentials with a phone-book entry. RasSetCredentials supersedes the RasSetEntryDialParams function, which may not be supported in future releases of Windows NT.
