// RNACALL.C - functions to call RNA dll to create connectoid
//
// HISTORY:
//
// 1/18/95 jeremys Cloned from RNA UI code
// 96/01/31 markdu Renamed CONNENTDLG to OLDCONNENTDLG to avoid
// conflicts with RNAP.H.
// 96/02/23 markdu Replaced RNAValidateEntryName with
// RASValidateEntryName
// 96/02/24 markdu Re-wrote the implementation of ENUM_MODEM to
// use RASEnumDevices() instead of RNAEnumDevices().
// Also eliminated IsValidDevice() and RNAGetDeviceInfo().
// 96/02/24 markdu Re-wrote the implementation of ENUM_CONNECTOID to
// use RASEnumEntries() instead of RNAEnumConnEntries().
// 96/02/26 markdu Replaced all remaining internal RNA APIs.
// 96/03/07 markdu Extend ENUM_MODEM class, and use global modem
// enum object.
// 96/03/08 markdu Do complete verification of device name and type
// strings passed in to CreateConnectoid.
// 96/03/09 markdu Moved generic RASENTRY initialization into
// its own function (InitRasEntry). Added a wait cursor
// during loading of RNA.
// 96/03/09 markdu Added LPRASENTRY parameter to CreateConnectoid()
// 96/03/09 markdu Moved all references to 'need terminal window after
// dial' into RASENTRY.dwfOptions.
// Also no longer need GetConnectoidPhoneNumber function.
// 96/03/10 markdu Moved all references to modem name into RASENTRY.
// 96/03/10 markdu Moved all references to phone number into RASENTRY.
// 96/03/11 markdu Moved code to set username and password out of
// CreateConnectoid into SetConnectoidUsername so it can be reused.
// 96/03/11 markdu Added some flags in InitRasEntry.
// 96/03/13 markdu Change ValidateConncectoidName to take LPCSTR.
// 96/03/16 markdu Added ReInit member function to re-enumerate modems.
// 96/03/21 markdu Work around RNA bug in ENUM_MODEM::ReInit().
// 96/03/24 markdu Replaced memset with ZeroMemory for consistency.
// 96/03/24 markdu Replaced lstrcpy with lstrcpyn where appropriate.
// 96/03/25 markdu Removed GetIPInfo and SetIPInfo.
// 96/04/04 markdu Added phonebook name param to CreateConnectoid,
// ValidateConnectoidName, and SetConnectoidUsername.
// 96/04/07 markdu NASH BUG 15645 Work around RNA bug where area code
// string is required even though it is not being used.
// 96/04/26 markdu NASH BUG 18605 Handle ERROR_FILE_NOT_FOUND return
// from ValidateConnectoidName.
// 96/05/14 markdu NASH BUG 22730 Work around RNA bug. Flags for terminal
// settings are swapped by RasSetEntryproperties.
// 96/05/16 markdu NASH BUG 21810 Added function for IP address validation.
// 96/06/04 markdu OSR BUG 7246 Add RASEO_SwCompression and
// RASEO_ModemLights to default RASENTRY.

NAME: InitRNA
SYNOPSIS: Loads the RNA dll (RASAPI32), gets proc addresses,
and loads RNA engine
EXIT: TRUE if successful, or FALSE if fails. Displays its
own error message upon failure.
NOTES: We load the RNA dll explicitly and get proc addresses
because these are private APIs and not guaranteed to
be supported beyond Windows 95. This way, if the DLL
isn't there or the entry points we expect aren't there,
we can display a coherent message instead of the weird
Windows dialog you get if implicit function addresses
can't be resolved.
