On second look, I think it’s supposed to be syslog(), not audit_msg(). The rest of the code in auparse/lru.c calls syslog(), and audit_msg() requires a `auparse_state_t *' parameter which the current code doesn’t supply. This causes compile-time warnings and probably runtime errors later if sanity_check_queue() were to actually be run. lru.c: In function ‘sanity_check_queue’: lru.c:148:14: warning: passing argument 1 of ‘auparse_msg’ makes pointer from integer without a cast [-Wint-conversion] audit_msg(LOG_DEBUG, "%s - corruption found %u", id, i); ^ In file included from lru.c:28:0: private.h:34:6: note: expected ‘auparse_state_t * {aka struct opaque *}’ but argument is of type ‘int’ void auparse_msg(auparse_state_t *au, int priority, const char *fmt, ...) ^ lru.c:148:25: warning: passing argument 2 of ‘auparse_msg’ makes integer from pointer without a cast [-Wint-conversion] audit_msg(LOG_DEBUG, "%s - corruption found %u", id, i); ^ In file included from lru.c:28:0: private.h:34:6: note: expected ‘int’ but argument is of type ‘char *’ void auparse_msg(auparse_state_t *au, int priority, const char *fmt, ...)
