I would suggest declaring a new struct:
const char *name;
And pass in an array of those. There are other possibilities -
Tim may have a different opinion.
History: GValue was called GParam and included a GParamSpec *;
it was meant for exactly this purpose. But we eventually decided
to change it to what it is now because the there were considerable
cases where you didn't want full parameter information and
just wanted a typed value
