How can I declare a vb function to access RAS functions like this?

DWORD RasEnumEntries (
  LPCTSTR reserved,               // reserved, must be NULL
  LPTCSTR lpszPhonebook,          // pointer to full path and  filename of
phone-book file
  LPRASENTRYNAME lprasentryname,  // buffer to receive  phone-book entries
  LPDWORD lpcb,                   // size in bytes of buffer
  LPDWORD lpcEntries              // number of entries written to buffer
);

typedef struct _RASENTRYNAME

     DWORD  dwSize;
    TCHAR  szEntryName[RAS_MaxEntryName + 1];
