[src/trunk]: src/usr.sbin/inetd inetd: prepare for lint's strict bool mode
details: https://anonhg.NetBSD.org/src/rev/9723dacd983b
branches: trunk
changeset: 985659:9723dacd983b
user: rillig <rillig%NetBSD.org@localhost>
date: Fri Sep 03 20:24:28 2021 +0000
description:
inetd: prepare for lint's strict bool mode
Lint's strict bool mode considers bool incompatible with the other
scalar types. This makes the type of expressions more visible in the
code. In particular, conditions of the form '!strcmp(...)' are no
longer allowed, they have to be written as 'strcmp(...) == 0'.
The operator '!' cannot be used with sep->se_wait since that has type
pid_t, not bool.
No change to the resulting binary.
