pretty sure I tried something like this about a week ago.
maybe last monday. it may have segv'd. but YES in cp_text.c
is ::
if (p)
{
fprintf (stdout, "%s", p);
L[i++] = p;
}
here "p" is the string or stringgs *within* /tmp/file/text.N.txt;
I planned on passing "L[]" to what you have above: "first text",
"second text".
in my example text.1.txt files I have (e.g.) "i am bringing this
laptop to the group so I can be more easily understood."

Re: more of a C question than GTK+3.0??
What I would do instead is:
GtkWidget **label[1000]; // if you have a dynamic number of labels,
consider using a GArray maybe
int i = 0;
label[i++] = gtk_label_new("first text"); // this will be label[0]
label[i++] = gtk_label_new("second text"); // this will be label[1]
…
After this, instead of creating a string "label1", you just need the
number 1, and can use this:
s = gtk_label_get_text(GTK_LABEL(label[1]));
where 1 can instead be a variable of int that holds 1:
int num = 1;
s = gtk_label_get_text(GTK_LABEL(label[num]));

I will heed your advise! a workaround may be in three *.c
files. but first:: sleep.

when I try to output the const char *s by casting the buf,
with is a string, "label1", it is NULL! Yes, no kidding.
the next msg explains why.
s = gtk_label_get_text(GTK_LABEL(labell);
iv'e looked at the following code:
label1 = gtk_label_new("1: This is the file name named talk.1.txt");
in another directory I have text files in /tmp/files/*; I think
the files over there grab the 10 files; *if* I stick the
output within gtk_label_new(). I think it may be a matter of
putting these files together and grabbing the content of the
talk.N.txt and putting them into gtk_label_new().
{ I am not explaining anything to this list, but at least I know
what I want to try }
