DESCRIPTION
Services form the middle layer of the Service Configuration Facility
repository tree. Services are children of a scope (see scf_scope_cre‐
ate(3SCF)) and have three sets of children:
Property groups
These hold configuration information shared by all
of the instances of the service. See scf_pg_cre‐
ate(3SCF), scf_iter_service_pgs(3SCF), and
scf_iter_service_pgs_typed(3SCF).
Instances
A particular instantiation of the service. See
scf_instance_create(3SCF).
A service groups one or more related instances and provides a shared
configuration for them.
An scf_service_t is an opaque handle that can be set to a single ser‐
vice at any given time. The scf_service_create() function allocates and
initializes a new scf_service_t bound to handle. The scf_ser‐
vice_destroy() function destroys and frees svc.
The scf_service_handle() function retrieves the handle to which svc is
bound.
The scf_service_get_parent() function sets sc to the scope that is the
parent of svc.
The scf_service_get_name() function retrieves the name of the service
to which svc is set.
The scf_scope_get_service() function sets svc to the service specified
by name in the scope specified by sc.
The scf_scope_add_service() function sets svc to a new service speci‐
fied by name in the scope specified by sc.
The scf_service_delete() function deletes the service to which svc is
set, as well as all of its children.
RETURN VALUES
Upon successful completion, scf_service_create() returns a new scf_ser‐
vice_t. Otherwise, it returns NULL.
Upon successful completion, scf_service_handle() returns the handle to
which svc is bound. Otherwise, it returns NULL.
Upon successful completion, scf_service_get_name() returns the length
of the string written, not including the terminating null byte. Other‐
wise, it returns -1.
Upon successful completion, scf_service_get_parent(),
scf_scope_get_service(), scf_scope_add_service(), and scf_ser‐
vice_delete() return 0. Otherwise, it returns -1.
ERRORS
The scf_service_create() function will fail if:
SCF_ERROR_INVALID_ARGUMENT
The value of the handle argument is NULL.
SCF_ERROR_NO_MEMORY
There is not enough memory to allocate an
scf_service_t.
SCF_ERROR_NO_RESOURCES
The server does not have adequate
resources for a new scope handle.
The scf_service_handle() function will fail if:
SCF_ERROR_HANDLE_DESTROYED
The handle associated with svc has been
destroyed.
The scf_service_get_name(), scf_service_get_parent(), and scf_ser‐
vice_delete() functions will fail if:
SCF_ERROR_DELETED
The service has been deleted by someone else.
SCF_ERROR_NOT_SET
The service is not set.
SCF_ERROR_NOT_BOUND
The handle is not bound.
SCF_ERROR_CONNECTION_BROKEN
The connection to the repository was lost.
The scf_service_delete() function will fail if:
SCF_ERROR_EXISTS
The service contains instances.
SCF_ERROR_NO_RESOURCES
The server does not have adequate resources
for a new scope handle.
The scf_scope_add_service() function will fail if:
SCF_ERROR_EXISTS
A {service,instance,property group} named name
already exists.
The scf_scope_get_service() function will fail if:
SCF_ERROR_BACKEND_ACCESS
The storage mechanism that the repos‐
itory server (svc.configd(1M)) chose for
the operation denied access.
SCF_ERROR_INTERNAL
An internal error occurred.
The scf_scope_add_service() and scf_scope_get_service() functions will
fail if:
SCF_ERROR_CONNECTION_BROKEN
The connection to the repository was lost.
SCF_ERROR_DELETED
The parent entity has been deleted.
SCF_ERROR_HANDLE_MISMATCH
The scope and service are not derived from the same handle.
SCF_ERROR_INVALID_ARGUMENT
The value of the name argument is not a valid service name.
SCF_ERROR_NO_RESOURCES
The server does not have the resources to complete the request.
SCF_ERROR_NOT_BOUND
The handle is not bound.
SCF_ERROR_NOT_FOUND
The service specified by name was not found.
SCF_ERROR_NOT_SET
The scope is not set.
The scf_scope_add_service() and scf_service_delete() functions will
fail if:
SCF_ERROR_PERMISSION_DENIED
The user does not have sufficient privileges to create or delete a
service.
SCF_ERROR_BACKEND_READONLY
The repository backend is read-only.
SCF_ERROR_BACKEND_ACCESS
The repository backend refused the modification.
The scf_error(3SCF) function can be used to retrieve the error value.
