JNI - ERREUR EXECUTION

Bonjour a tous,

je souhaite beneficier de votre aide pour m aider a resoudre une erreur que je rencontre lors de l execution de mon programme JNI. En effet jai ecrit des fonctions en C permettant de creer une queue ipc, ensuite recuperer son identifiant et le stocker dans une memoire partagee. L objectif est de permettre aux autres programmes de pouvoir recuperer l identifinat de la queue de la memoire partagee afin de lire ou ecrire un message.
Ci-dessous les differents elements et l erreur rencontree :

1. La classe java
Code:
