DSM_Entry use in C#

[da9287]

I am using SDM_Entry with Control, Identity and GetDefault, the last parameter requires IntPtr. I have TwIdentity = srcds that I need to pass in place of the last argument. Does anyone know how to pass it in place of th last parameter or how to convert it to IntrPtr in C#? I have experimented to use unsafe &srcds. As it seems C# does not allow the address conversion of struct.

Can anyone advie?

Never mind I have figured it:

[DllImport(“twain_32.dll”, EntryPoint = “#1”)]
private static extern TwRC foo([In, Out] TwIdentity origin, IntPtr zeroptr, TwDG dg, TwDAT dat, TwMSG msg, [In, Out] TwIdentity idds);
