With gtk3, how do I make a write to the clipboard presistant?

Question

I stink at reading C code.gtk

In the sample clipboard_simple.c

it states

// NOTE: If you test this without a clipboard manager running, the
// new text saved to the clipboard will disappear as soon as this
// program exits.

xclip does not have this issue, and I can't figure out why.

How do I make a (text) write to the clipboard persistent?

Many thanks,

New info:

I do believe the missing piece of the puzzle is: gtk-clipboard-store

void
gtk_clipboard_store (GtkClipboard *clipboard);

Would someone point to the structure of GtkClipboard? I think it is buried somewhere in /usr/include/gtk-3.0/gtk/gtkclipboard.h, but I can not figure it out.

Edit: if I am not mistaken, it is just a C pointer to a 64 bit integer
