From: Zhao Hongjiang <[email protected]> Strings should be copied with strlcpy instead of strncpy when they will later be printed via %s. This guarantees that they terminate with a NUL '\0' character and do not run pass the end of the allocated string.
This is only for sample code, but it should stil represent a good role model.
