The Lazarus backend interface unit is as follows but still unfinished:
----------------------------------------
unit backend;
{$mode objfpc}{$H+}
interface
uses
Classes, SysUtils, stdctrls;
procedure Backend_Save(essid, pw: string);
procedure Backend_Save_Connect(essid, pw: string);
function Backend_Query_Connect(connection: string; var pw: string): boolean;
function Backend_Delete_Connect(essid: string): boolean;
function Backend_Connection_Connect(essid: string): boolean;
function Backend_Disconnect_Active_Connection: boolean;
procedure Backend_Scan(aListBox: TListBox);
procedure Backend_Load_Existing(aListBox: TListBox);
implementation
const
opSave = 0;
opSaveConnect = 1;
opQueryConnect = 2;
opDeleteConnect = 3;
opConnectionConnect = 4;
opDisconnectActiveConnection = 5;
opScan = 6;
opLoadExisting = 7;
procedure Backend_Save(essid, pw: string);
begin
// backend opSave essid pw
end;
procedure Backend_Save_Connect(essid, pw: string);
begin
// backend opSaveConnect essid pw
end;
function Backend_Query_Connect(connection: string; var pw:string): boolean;
begin
// backend opQueryConnect essid pw
end;
function Backend_Delete_Connect(essid: string): boolean;
begin
// backend opDeleteConnect essid
result := true;
end;
function Backend_Connection_Connect(essid: string): boolean;
begin
// backend opConnectionConnect essid
end;
function Backend_Disconnect_Active_Connection: boolean;
begin
// backend opDisconnectActiveConnection
end;
procedure Backend_Scan(aListBox: TListBox);
begin

end;
procedure Backend_Load_Existing(aListBox: TListBox);
begin

end;
end.
