Struct dpdk_unix::Daemonize [−][src]
pub struct Daemonize { pub working_folder_path: PathBuf, pub pid_folder_path: PathBuf, pub user_name: CString, }
An object that can be used with a configuration file (eg via Serde) to configure a daemon.
The following are done:-
- umask is set to just the current user
- Checks are made to check the program is not running with the set uid bit set ('setuid' or 'suid').
- A PID file is created
- standard in is redirected to
/dev/null
. - standard out and error are redirected to
/dev/null
. fprintf
and friends using theFILE
API are redirected to syslog on Linux (this is probably also possible to implement for FreeBSD - see https://mischasan.wordpress.com/2011/05/25/redirecting-stderr-to-syslog/).- Double forking and a new session are created.
- Real and effective user and group ids are changed.
- Additional groups from
/etc/group
, if any, are assigned. - Environment variables are populated if missing (
IFS
,PATH
) - User environment variables are overwritten (
HOME
,LOGNAME
,USER
).
Fields
working_folder_path: PathBuf
The folder path to use as the 'current working directory' (CWD).
Equivalent functionality to the shell command chdir
.
Defaults to /
.
pid_folder_path: PathBuf
A folder path in which to put a PID file.
This uses the processes' name for the actual file base name.
Defaults to /var/run
.
user_name: CString
An user name that must exist in /etc/passwd
(or the local equivalent).
Use to discover runtime user and groups to change to and the home folder of the running user.
