DESCRIPTION¶
These functions provide a means of querying the dependencies of OpenRC services.rc_deptree_update
() updates the service
dependency tree, normally /lib/rc/init.d/deptree.
rc_deptree_update_needed
() checks to see if the
dependency tree needs updated based on the mtime of it compared to
/etc/init.d, /etc/conf.d,
/usr/local/etc/init.d,
/usr/local/etc/conf.d,
/etc/rc.conf and any files specified by a
service.
rc_deptree_load
() loads the deptree and
returns a pointer to it which needs to be freed by
rc_deptree_free
() when done.
rc_deptree_depend
(),
rc_deptree_depends
() and
rc_deptree_order
() return a list of services from
the deptree based on the type or
types of dependency. options can
be a bitmask of RC_DEP_TRACE and
RC_DEP_STRICT. RC_DEP_TRACE
follows each services dependencies right down to the first service needed
and RC_DEP_STRICT only lists services actually needed
or in the runlevel.
IMPLEMENTATION NOTES¶
Each function that returns RC_STRINGLIST * should be freed by callingrc_stringlist_free
() when done.
