EINTR (Interrupted system call)

Liste non exhaustive des fonctions pouvant être interrompues avec un code d'erreur EINTR : select, accept4, poll, recv, read, write.

Ces fonctions précédentes renvoient -1 en cas d'échec et la variable errno (thread-safe) renvoie EINTR en cas d'interruption.

La méthode simple est de faire une boucle autour de l'appel avec la condition retval == -1 && errno == EINTR.

La méthode complète est de savoir d'où vient cette interruption système : EINTR and What It Is Good For Archive du 05/11/2012 le 17/10/2019
