This optional key is used as a hint to <literal>launchctl(1)</literal> that it should not submit this job to launchd when
|
2016-11-01 20:25:22 +00:00
|
|
|
loading a job or jobs. The value of this key does NOT reflect the current state of the job on the run-ning running

|
|
|
ning system. If you wish to know whether a job is loaded in launchd, reading this key from a configura-tion configuration
|
|
|
|
|
tion file yourself is not a sufficient test. You should query launchd for the presence of the job using
|
2017-10-19 19:55:37 +00:00
|
|
|
the <literal>launchctl(1)</literal> list subcommand or use the ServiceManagement framework's

<literal>SMJobCopyDictionary()</literal> method.

2017-10-19 19:55:37 +00:00

is changed with the [-w] option of the <literal>launchctl(1)</literal> load and unload subcommands. These subcommands no
|
2016-11-01 20:25:22 +00:00
|
|
|
longer modify the configuration file, so the value displayed in the configuration file is not necessar-ily necessarily

ily the value that <literal>launchctl(1)</literal> will apply. See <literal>launchctl(1)</literal> for more information.

rarely.

This optional key describes, at a high level, the intended purpose of the job. The system will apply

|
resource limits based on what kind of job it is. If left unspecified, the system will apply light
|
|
|
|
|
resource limits to the job, throttling its CPU usage and I/O bandwidth. The following are valid values:
|
|
|
|
|
|

|
|
|
Background
|
|
|
|
|
Background jobs are generally processes that do work that was not directly requested by the user.

|
The resource limits applied to Background jobs are intended to prevent them from disrupting the
|
|
|
|
|
user experience.

This optional key is used to specify launch on demand sockets that can be used to let launchd know when

cols (e.g. http vs. ftp vs. DNS...). At check-in time, the value of each Sockets dictionary key will
