Example:
NB : The example hereunder works perfectly with a number of elements <=
100,000 but crashes if one when the number of elements to insert in the List
is >= 1000,000 .

using Gee;
using Posix;
// Struct to hold key, values pairs
struct pair {

// Comparison function for stucts

if( a.freq > b.freq) return -1;
else if( a.freq < b.freq) return +1;
else return 0;
}
// Equality function for structs
bool equals (pair a, pair b) {
if (Posix.strcmp(a.word, b.word) ==0 ) return true;
else return false;
}
int main(string[] args) {
//List
var L = new LinkedList<pair?>( (EqualFunc) equals);
// Insert in List (to sort)
pair p = pair();
for (var i=0; i<1000000; i++) {
p.word = "test";
p.freq = 1;
L.add(p);
}
// Sort list
L.sort( (CompareFunc)comp );
// Freq distribution
var i = 0;

Posix.printf("(%u,\t '%s')\n", item.freq, item.word);
i++;
if (i > 10) break;
}
return 0;
