  • If you want to redirect syslogd output to slogger, edit /etc/syslog.conf and specify an action to send the log messages to /dev/console, or specify the LOG_CONS flag when you call openlog().
  • You can't redirect slogger output to slogger2 in general, but if a program uses the slogger APIs, you can preload the libslog2shim.so library when you start the program, in order to redirect its logs.
  • The size argument for the -l option is in kilobytes.

Errata

devnp-asix.so
This is a native io-pkt driver.
/etc/dhclient-dhcpv6.conf, /etc/dhcpd-dhcpv6.conf
We've corrected the names of the IPv6 files.
dumper
We've corrected the forms of the -U option's argument.
/etc/exports
We've corrected the name of IPPORT_RESERVED.
fs-cifs
Write buffering is disabled in the code, whether or not you specify the -b option.
fs-qnx6.so
We've corrected the name of the DCMD_FSYS_FILE_FLAGS devctl() command.
fsencrypt
  • The length of the key depends on the type of encryption; see the description of the -t option.
  • In order for you to tag files for migration, the source and destination domains must be unlocked.
  • A domain doesn't have to be unlocked for you to delete it.
  • We've corrected the descriptions of the .[salt.]str and #str forms of the -k option.
  • You must use the -t option to specify the type of encryption when you use the change-key, check-key, unlock, and write-key commands.
  • You can specify a domain of 0 (using the -d option) to remove encryption.
  • If you assign a domain to a directory or empty file, the domain replaces any domain previously assigned to the path.
gcc
If you want new() to return NULL instead of throwing an exception, you can provide a custom new handler via std::set_new_handler() to do so, or use std::nothrow.
gcov
We've corrected the name of the profile-arcs option.
inflator
None of the current flash filesystem drivers supports compression.
less
The v command invokes vi if the EDITOR environment variable isn't set.
logger
The -f, -i, -p, -s, and -t options are QNX Neutrino extensions. If you don't specify the -t option, the current user ID is used as a tag.
lsm-qnet.so
If you want Qnet to run on your system, you must load it into the network manager.
mkqnx6fsimg
We've corrected the example.
mount
The -u option does preserve options that you specified for the block filesystem.
mount_ifs
  • This utility runs on QNX Neutrino, not on development hosts.
  • You must specify the -f and -m options.

pppoectl
The /dev/io-net/ppp_en, /etc/ppp/pppoe-down, and /etc/ppp/pppoe-up files have no use under pppoectl.
/etc/pf.conf
We don't currently ship pflog or pflogd. If you load lsm-pf-v4.so or lsm-pf-v6.so, io-pkt creates a pflog0 interface. If you enable logging, the logged packets are sent to this interface, and you can use tcpdump to display them.
qcc
  • If you want new() to return NULL instead of throwing an exception, you can provide a custom new handler via std::set_new_handler() to do so, or use std::nothrow.
  • The -nostdlib option makes qcc not use the ld_startup_* or ld_stdlib sections.
random
We've corrected the forms of the -U option's argument.
route
The value of the family variable for the flush command must be -inet or -inet6.
slm
  • We've corrected the names of the PROCMGR_EVENT_PATHSPACE and PROCMGR_EVENT_DAEMON_DEATH system events.

sysctl
The values for net.inet.tcp.keepidle, net.inet.tcp.keepintvl, net.inet6.tcp6.keepidle, and net.inet6.tcp6.keepintvl are in clock ticks, not milliseconds.
tcpdump
The -K and -z options aren't implemented.
traceprinter
The default name of the file that stores the trace information to be displayed is /dev/shmem/tracebuffer.kev.
waitfor
Use a space instead of a colon to separate the wait_time and poll_ms arguments.
