// Get the next expanded file from an expander.

//

//
// C SYNOPSIS
//
// #include "arclib.h"

//
// char *ALExpanderGetNextFile( hALExpander this_object );
//
// VB SYNOPSIS
//
// Declare Function ALExpanderGetNextFile Lib "AL20LW"
// Alias "ALExpanderGetNextFileVB"
// (ByVal this_object&) As String
//
// DELPHI SYNOPSIS
//
// function ALExpanderGetNextFile( this_object : hALExpander ) : PChar;
//
// ARGUMENTS
//
// this_object : A handle for (pointer to) an ALWildCardExpander
// object.
//
// DESCRIPTION
//
// There are several different versions of the C++ function. You
// can find them in: ..\CPP_FS.DOS\WILDDOS.CPP, et. al. They
// have a complete explanation of how the function works.
//
// This file just has the C/VB/Delphi translation code. These routines
// call the C++ member functions, which is found elswhere. See those
// files for details on what happens for each O/S.
//
// RETURNS
//
// A string containing the next expanded wild card generated by
// the wild card engine. Note that under C, you will get a pointer
// to a string that is residing inside the ALWildCardExpander
// object, which you are free to copy or duplicate. The VB translation
// function actually creates a new string using the ALCreateVBString
// function.
