Thanks about the solution.
I thought about this solution earlier as fail safe, but it just didn't seen
right to
force the user to use my way all along main(and not natural).
However, I've ended up using another way to make this easy in Vala:
namespace Max {
[CCode (has_target="false")]
public delegate bool ArgsBoolFunc ([CCode (array_length_pos = 0.9)] ref
unowned string[] args);
private delegate bool ArgsBoolFuncC (int* argsc, char*** argsv);
public bool pass_args_bool (ArgsBoolFunc func) {
ArgsBoolFuncC func_c = (ArgsBoolFuncC)func;
return func_c (argsc, argsv);
}
}
I've also copy the code for the void and int types.
This hide complexity from the user which I see as the best solution so far.
I've just hoped that there could be some pointer to "ref" conversion in Vala,
like:
void* pointer
func ((ref)pointer)
Thanks again,
Tal
