Re: [Vala] User managed memory?

["Thijs Vermeir" <thijsvermeir gmail com>]

Hello,

there is already a delete keyword defined for pointers, and I think it
is the only
way to free pointers, if you don't use the delete statement you are
leaking the allocated memory,
here is an example:

== example.vala
using GLib;

public struct Example {
  public int first;
  public int second;
}

public static void main (string[] args) {
  Example* example = new Example[1];
  message ("Example created");
  delete example;
  message ("Example deleted");
}
==

and this will be translated to this:
== example.c
...
Example* example;
example = g_new0 (Example, 1);
g_message ("example.vala:10: Example created");
g_free (example);
g_message ("example.vala:12: Example deleted");
...
==

Gr,
Thijs
