Question : interpreting C++ code into VB.NET

I am trying to use a vendor-supplied dll written in C code where the declaration in the dll looks like this:
extern "C" __stdcall int tira_get_captured_data (
const unsigned char** data,
int* size );

How does that translate into a VB.Net compatible function?

Thanks in advance.

(Maybe useful information here, but not simple enough for me...

             <DllImport("tira2.dll", CharSet:=CharSet.Auto)> _
    Private Shared Function tira_get_captured_data(ByRef data As IntPtr, ByRef size As Integer) As Integer
    End Function

    <DllImport("tira2.dll", CharSet:=CharSet.Auto)> _
    Private Shared Function tira_delete(ByVal ptr As IntPtr) As Integer
    End Function


    Sub Tira()

        Dim data As IntPtr = IntPtr.Zero
        Dim dataSize As Integer = 0
        Dim res As Integer = 0

        res = tira_get_captured_data(data, dataSize)

        '//TODO: Work with (data) pointer.

        If data.ToInt32 <> 0 Then
            ' free heap memory
            res = tira_delete(data)
        End If

    End Sub
