Write a Delphi XE5 interface based on c# code to talk to an C DLL from Delphi

Dear Delphi programmers, We are looking for a skilled Delphi programmer with good C++ C# knowledge able to create an interface header for a C++ DLL that will be used by our Delphi application. Testing can’t be outsourced since the DLL is controlling a Hardware device. The DLL Exports 88 functions What we have: the code c# class to call the functions of the DLL the compiled DLL C Source of the DLL is not available And What th c# code looks like: using System; using [login to view URL]; using [login to view URL]; using [login to view URL]; using [login to view URL]; using [login to view URL]; namespace sbxpc { class SBXPCDLL { [DllImport("[login to view URL]", CallingConvention = [login to view URL])] static extern void _DotNET(); public static void DotNET() { _DotNET(); } [DllImport("[login to view URL]", CallingConvention = [login to view URL])] static extern byte _EnableDevice(Int32 dwMachineNumber, byte bFlag); public static bool EnableDevice(Int32 dwMachineNumber, byte bFlag) { return _EnableDevice(dwMachineNumber, bFlag) > 0; } #region Not Tested Part 1 [DllImport("[login to view URL]", CallingConvention = [login to view URL])] static extern byte _SetMachineType(Int32 dwMachineNumber, ref IntPtr lpszMachineType); public static bool _SetMachineType(Int32 dwMachineNumber, string lpszMachineType) { IntPtr string_in = [login to view URL](lpszMachineType); try { return _SetMachineType(dwMachineNumber, ref string_in) > 0; } catch (Exception) { return false; } finally { [login to view URL](string_in); } } [DllImport("[login to view URL]", CallingConvention = [login to view URL])] static extern byte _GetEnrollData(Int32 dwMachineNumber,Int32 dwEnrollNumber,Int32 dwEMachineNumber,Int32 dwBackupNumber, IntPtr dwMachinePrivilege, ref IntPtr dwEnrollData, IntPtr dwPassWord); public static bool GetEnrollData(Int32 dwMachineNumber, Int32 dwEnrollNumber, Int32 dwEMachineNumber, Int32 dwBackupNumber, out Int32 dwMachinePrivilege, byte[] dwEnrollData, out Int32 dwPassWord) { dwMachinePrivilege = 0; dwPassWord = 0; byte[] privilege = new byte[4]; byte[] password = new byte[4]; GCHandle gh_privilege = [login to view URL](privilege, [login to view URL]); GCHandle gh_password = [login to view URL](password, [login to view URL]); GCHandle gh_enroll_data = [login to view URL](dwEnrollData, [login to view URL]); try {
