RasGetSubEntryProperties
[New - Windows NT]
The RasGetSubEntryProperties function retrieves information about a subentry for a specified phone-book
entry.
DWORD RasGetSubEntryProperties(
LPTSTR lpszPhonebook,
| // pointer to full path and filename of phone-book file
| LPTSTR lpszEntry,
| // pointer to an entry name
| DWORD dwSubEntry,
| // index of the subentry
| LPRASSUBENTRY lpRasSubEntry,
| // pointer to structure that receives information about subentry
| LPDWORD lpdwcb
| // size, in bytes, of the structure
| );
|
|
Parameters
lpszPhonebook
Windows NT: 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 containing the name of an existing entry
in the phone book.
dwSubEntry
Specifies the one-based index of the subentry.
lpRasSubEntry
Pointer to a RASSUBENTRY structure followed by additional bytes for the alternate phone number list,
if there is one. The structure receives the information about the specified
subentry. Before calling the function, set the dwSize member of the structure to sizeof(RASSUBENTRY) to identify the version of the structure. This parameter can be NULL.
lpdwcb
Pointer to a variable that contains the size, in bytes, of the lpRasSubEntry buffer. On return, the function sets this variable to the number of bytes
returned, or the number of bytes required if the buffer is too small. This
parameter can be NULL if lpRasSubEntry is NULL.
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 function was called with an invalid parameter.
| ERROR_BUFFER_INVALID
| The address or buffer specified by lpRasSubEntry is invalid.
| ERROR_BUFFER_TOO_SMALL
| The lpRasSubEntry buffer is too small. The lpdwcb variable receives the required buffer size.
| ERROR_CANNOT_OPEN_PHONEBOOK
| The phone book is corrupted or is missing components.
| ERROR_CANNOT_FIND_PHONEBOOK_ENTRY
| The phone-book entry does not exist.
|
Remarks
A RAS phone-book entry can have zero or more subentries, each minimally
consisting of a device and a phone number. A phone-book entry with multiple
subentries can be configured to dial the first available or all subentries when the
entry is dialed.
Use the RasGetEntryProperties function to retrieve a RASENTRY structure containing information about the subentries of a phone-book entry.
The dwSubEntries member indicates the number of subentries and the dwDialMode member indicates the dialing configuration.
