// DESCRIPTION
//
// This file contains all the C translation layer routines for the
// pure virtual member functions in ALEntryList, as well as some
// member access routines.
//
// Functions that simply provide a translation layer for an existing C++
// function are always located in the same file as the C++ function. The
// functions in this file don't have any existing C functions to attach
// to, since they implement either pure virtual functions or member access
// routines.

// SHORT DESCRIPTION
//
// Get the integer status code for an entry list.
//
// C++ SYNOPSIS
//
// None. C++ programmers have direct access to the ALEntryList::mStatus
// member, so they can directly call ALEntryList::mStatus.GetStatusCode().
//
// C SYNOPSIS
//
// #include "arclib.h"
//
// int ALEntryListGetStatusCode( hALEntryList this_object );
//
// VB SYNOPSIS
//
// Declare Function ALEntryListGetStatusCode Lib "AL20LW"
// (ByVal this_object&) As Integer
//
// DELPHI SYNOPSIS
//
// function ALEntryListGetStatusCode( this_object : hALEntryList ) : Integer;
//
// ARGUMENTS
//
// this_object : A handle for (pointer to) an ALEntryList object.
//
// DESCRIPTION
//
// This is the C/VB wrapper function for the C++ access function
// ALEntryList::mStatus::GetStatusCode(). For details on how the member
// function in ALName works, see ALName::GetStatusCode().
//
// All that happens here is that the arguments are checked for correct
// type (when in debug mode), and a call is made to the appropriate
// member function, with some casting.
//
// RETURNS
//
// An integer that contains the current status code for the object.
// Note that values of < 0 always indicate an error conditions.

//
// SHORT DESCRIPTION
//
// Return the short status string from the ALEntryList::mStatus member.
//
// C++ SYNOPSIS
//
// None. C++ programmers have access to the ALEntryList::mStatus member,

// ARGUMENTS
//
// this_object : A handle for (pointer to) an ALEntryList object.
// We want to get the string translation of the error

//
// DESCRIPTION
//
// This is the C wrapper function that provides access to the mStatus
// member. This routine calls GetStatusString for the member, returning
// a short descriptive character string.
//
// Note that we have a slightly modified function to return strings
// to VB programmers.
//
// RETURNS
//
// Always returns a pointer to a short string translation of the
// current error code.
