Description Allison Karlitskaya (desrt) 2011-04-13 02:28:42 UTC 
void print_size<G> () {
    print ("the answer is %lu\n", sizeof (G));
}

void main () {
    print_size<int>();
}

"the answer is 8"
Comment 1 Allison Karlitskaya (desrt) 2011-04-13 02:30:45 UTC 
Of course, this is because Vala uses 'sizeof (gpointer)' here.

Worse: glib doesn't have a facility for answering this question correctly.

My particular use case is that I'm trying to write a function to resize arrays and I want to use it with an array of ints.
Comment 2 Luca Bruno 2011-04-16 08:26:47 UTC 
GType provides no size information for fundamental types like int through g_type_query?
