You mean like that ?
ns->ucount_max[UCOUNT_RLIMIT_NPROC] = rlimit(RLIMIT_NPROC) <= LONG_MAX ?
rlimit(RLIMIT_NPROC) : LONG_MAX;
ns->ucount_max[UCOUNT_RLIMIT_MSGQUEUE] = rlimit(RLIMIT_MSGQUEUE) <= LONG_MAX ?
rlimit(RLIMIT_MSGQUEUE) : LONG_MAX;
ns->ucount_max[UCOUNT_RLIMIT_SIGPENDING] = rlimit(RLIMIT_SIGPENDING) <=
LONG_MAX ?
rlimit(RLIMIT_SIGPENDING) : LONG_MAX;
ns->ucount_max[UCOUNT_RLIMIT_MEMLOCK] = rlimit(RLIMIT_MEMLOCK) <= LONG_MAX ?
rlimit(RLIMIT_MEMLOCK) : LONG_MAX;
