The scf_iter_create() function creates a new iterator associated with handle. The scf_iter_destroy() function destroys an iteration.
The scf_iter_reset() function releases any resources involved with an active iteration and returns the iterator to its initial state.
The scf_iter_handle_scopes(), scf_iter_scope_services(), scf_iter_service_instances(), scf_iter_instance_snapshots(), scf_iter_service_pgs(), scf_iter_instance_pgs(), scf_iter_snaplevel_pgs(), scf_iter_pg_properties(), and scf_iter_property_values() functions set up a new iteration of all the children of parent of a particular type.
The scf_iter_service_pgs_typed(), scf_iter_instance_pgs_typed(), and scf_iter_snaplevel_pgs_typed() functions iterate over the child property groups of parent, but restrict them to a particular property group type.
The scf_iter_instance_pgs_composed() function sets up a new iteration of the composed view of instance's children at the time snapshot was taken. If snapshot is NULL, the current properties are used. The composed view of an instance's properties is the union of the properties of the instance and its ancestors. Properties of the instance take precedence over properties of the service with the same name, including property group name. Property groups retrieved with this iterator might not have instance as their parent and properties retrieved from such property groups might not have the indicated property group as their parent. If instance and its parent have property groups with the same name but different types, the properties in the property group of the parent are excluded. The scf_iter_instance_pgs_typed_composed() function behaves as scf_iter_instance_pgs_composed(), except the property groups of the type pgtype are returned.
The scf_iter_next_scope(), scf_iter_next_service(), scf_iter_next_instance(), scf_iter_next_snapshot(), scf_iter_next_pg(), scf_iter_next_property(), and scf_iter_next_value() functions retrieve the next element of the iteration.
Upon successful completion, scf_iter_create() returns a pointer to a new iterator. Otherwise, it returns NULL.
Upon successful completion, scf_iter_handle() returns the handle associated with iter. Otherwise it returns NULL.
Upon successful completion, scf_iter_handle_scopes(), scf_iter_scope_services(), scf_iter_service_instances(), scf_iter_instance_snapshots(), scf_iter_service_pgs(), scf_iter_instance_pgs(), scf_iter_snaplevel_pgs(), scf_iter_pg_properties(), scf_iter_property_values(), scf_iter_service_pgs_typed(), scf_iter_instance_pgs_composed(), scf_iter_instance_pgs_typed(), scf_iter_instance_pgs_typed_composed(), and scf_iter_snaplevel_pgs_typed() return 0. Otherwise, they return -1.
Upon successful completion, scf_iter_next_scope(), scf_iter_next_service(), scf_iter_next_instance(), scf_iter_next_snapshot(), scf_iter_next_pg(), scf_iter_next_property(), and scf_iter_next_value() return 1. If the iterator is complete, they return 0. Otherwise, they return -1.
The scf_iter_create() function will fail if:
The handle argument is NULL.
There is no memory available.
The server does not have adequate resources for a new iteration.
The scf_iter_handle() function will fail if:
The handle associated with iter has been destroyed.
The scf_iter_handle_scopes(), scf_iter_scope_services(), scf_iter_service_instances(), scf_iter_instance_snapshots(), scf_iter_service_pgs(), scf_iter_instance_pgs(), scf_iter_instance_pgs_composed(), scf_iter_snaplevel_pgs(), scf_iter_pg_properties(), scf_iter_property_values(), scf_iter_service_pgs_typed(), scf_iter_instance_pgs_typed(), scf_iter_instance_pgs_typed_composed(), and scf_iter_snaplevel_pgs_typed() functions will fail if:
The parent has been deleted.
The parent is not set.
The handle is not bound.
The connection to the repository was lost.
The iter and parent arguments are not derived from the same handle.
The scf_iter_service_pgs_typed(), scf_iter_instance_pgs_typed(), scf_iter_instance_pgs_typed_composed(), and scf_iter_snaplevel_pgs_typed() functions will fail if:
The pgtype argument is not a valid property group type.
The scf_iter_next_service(), scf_iter_next_instance(), scf_iter_next_snapshot(), scf_iter_next_pg(), scf_iter_next_property(), and scf_iter_next_value() functions will fail if:
The parent the iterator is attached to has been deleted.
The scf_iter_next_scope(), scf_iter_next_service(), scf_iter_next_instance(), scf_iter_next_snapshot(), scf_iter_next_pg(),scf_iter_next_property(), and scf_iter_next_value() functions will fail if:
The iterator is not set.
The requested object type does not match the type the iterator is walking.
The handle is not bound.
The iter and parent arguments are not derived from the same handle.
The connection to the repository was lost.
The scf_error(3SCF) function can be used to retrieve the error value.
Example 1 Iterate over all instances under a service.
scf_iter_t *iter = scf_iter_create(handle); if (iter == NULL || scf_iter_service_instances(iter, parent) == -1) { /* failure */ } while ((r = scf_iter_next_instance(iter, child)) > 0) { /* process child */ } if (r < 0) { /* failure */ } scf_iter_destroy(iter);
Example 2 Connect to the repository, walk all services and instances and print their FMRIs.
scf_handle_t *handle = scf_handle_create(SCF_VERSION); scf_scope_t *scope = scf_scope_create(handle); scf_service_t *svc = scf_service_create(handle); scf_instance_t *inst = scf_instance_create(handle); scf_iter_t *svc_iter = scf_iter_create(handle); scf_iter_t *inst_iter = scf_iter_create(handle); size_t sz = scf_limit(SCF_LIMIT_MAX_FMRI_LENGTH) + 1; char *fmri = malloc(sz + 1); int r; if (handle == NULL || scope == NULL || svc == NULL || inst == NULL || svc_iter == NULL || inst_iter == NULL || fmri == NULL) { /* failure */ } if (scf_handle_bind(handle) == -1 || scf_handle_get_scope(handle, SCF_SCOPE_LOCAL, scope) == -1 || scf_iter_scope_services(svc_iter, scope) == -1) { /* failure */ } while ((r = scf_iter_next_service(svc_iter, svc)) > 0) { if (scf_service_to_fmri(svc, fmri, sz) < 0) { /* failure */ } puts(fmri); if (scf_iter_service_instances(inst_iter, svc) < 0) { /* failure */ } while ((r = scf_iter_next_instance(inst_iter, inst)) > 0) { if (scf_instance_to_fmri(inst, fmri, sz) < 0) { /* failure */ } puts(fmri); } if (r < 0) break; } if (r < 0) { /* failure */ } scf_handle_destroy(handle); scf_scope_destroy(scope); scf_service_destroy(svc); scf_instance_destroy(inst); scf_iter_destroy(svc_iter); scf_iter_destroy(inst_iter);
