6.22 errno -- Sistema standard dei simboli di errore

Questo modulo rende disponibile il sistema standard dei simboli di errore di sistema (errno). Il valore di ogni simbolo il corrispondente valore intero. Il nome e la descrizione vengono presi in prestito dal file linux/include/errno.h, che dovrebbe contenerli tutti.

errorcode
Il dizionario che fornisce una mappa dal valore di errno al nome della stringa del sistema sottostante. Per esempio, errno.errorcode[errno.EPERM] mappa a 'EPERM'.

Per tradurre un codice numerico di errore in un messaggio di errore, usate la funzione os.strerror().

Della seguente lista, i simboli che non vengono usati nella piattaforma corrente non vengono definiti dal modulo. La lista specifica dei simboli definiti disponibile come errno.errorcode.keys(). I simboli disponibili possono contenere:
