You could start with this 'gaul.vapi'. (attachment)
There are two alternatives for 'ga_seed_boolean_random': you can bind it
either as static function or as instance method of class 'Population'.
All classes are [Compact], because they are non-GObject types.
While writing a vapi file by hand it is helpful to look at the generated
C code of a test program that uses the newly added functions:
$ valac gaultest.vala --pkg gaul --vapidir . -C
Sometimes you can rely on the default name prefixes and sometimes you
must override them with [CCode (...)] attributes.

UNKNOWN,
BINOMIAL,
EXPONENTIAL
}
[Compact]
[CCode (cname="population", free_function = "ga_extinction")]
public class Population {
public Population (int stable_size, int num_chromosome,
int len_chromosome);
public void set_mutation (double mutation);
// Alternative A:
[CCode (cname = "ga_seed_boolean_random")]
public bool seed_boolean_random (Entity adam);
}
[Compact]
[CCode (cname="entity")]
public class Entity {
}
// Alternative B:
public static bool seed_boolean_random (Population pop, Entity adam);
}
