The RasCreatePhonebookEntry function creates a new phone-book entry. The function displays a dialog box in which the user types information for the phone-book entry.
Windows NT: The RasCreatePhonebookEntry function calls the RasEntryDlg function. Applications written for Windows NT version 4.0 should use RasEntryDlg.
DWORD RasCreatePhonebookEntry(
  HWND hwnd,  // handle to the parent window of the dialog box
  LPCTSTR lpszPhonebook
              // pointer to the full path and filename of the 
              // phone-book file
);
 Windows 95: Dial-up networking stores phone-book entries in the registry rather than in a phone-book file.
If the function succeeds, the return value is zero.
If the function fails, the return value is the following error code:
| Value | Description | 
|---|---|
| ERROR_CANNOT_OPEN_PHONEBOOK | |
| The phone book is corrupted or missing components. | |
