here's the way I've done it so far:
I've used readdir( DIR *d) and more to find the text[n].txt
file names. then, in a 1998 c++ file I find these txt names
by using essentially {psedocode):
infp = fopen(filename[i], "r")
while (fgets(buffer[i], sizeof buffer, infp))
fclose(infp);
that's an immediate re-translation from c++ to C.
thanks, polyt. I will put this last of several pieces of code
together until I've got my several buffer[i] copied into the
GTK label[i].
FWIW: the reason I want to have these several "labels" in a
wudget//widows is to make the program less clumsy. it does
work as-is; but it can get clumsy.
