Routine Description:
Loads the custom dll if specified in the ras phonebook
entry and Gets the entry point specified by the dwFnId.
The possible entry points retrieved are RasCustomDialDlg
and RasCustomEntryDlg.
Arguments:
lpszPhonebook - The phonebook path to be used to look for
the entry. This is not allowed to be NULL.
lpszEntry - The EntryName to be used. This is not allowed
to be NULL.
pfCustomDllSpecified - Buffer to hold a BOOL indicating if
a custom dll was specified for the
entry.
pfnCustomEntryPoint - Buffer to hold the address of the
Custom Entry Point.
phInstDll - Buffer to hold the HINSTANCE of the loaded
dll.
dwFnId - Function Id indicating which Entry Point to load.
The possible values are CUSTOM_RASDIALDLG and
CUSTOM_RASENTRYDLG.
Return Value:
ERROR_SUCCESS if successful
