Is there an example of InputText?

[PrimeraTech]

I have been trying by trial and error to get C# to be happy with my syntax for ImGui.InputText ().

Can anyone provide a single example that will compile and work?

The function prototype is:
public static bool InputText(string label, char* buf, UIntPtr buf_size, ImGuiInputTextFlags flags = (ImGuiInputTextFlags)(0), ImGuiInputTextCallback callback = null, IntPtr user_data = default)

How is a char * variable defined in c# to be compatible with the second parameter?

The following code compiles but does not work:

string foo = "this is a test";
unsafe
{
ImGui.InputText("xx", (char*)&foo, new UIntPtr(10));
}
