DESCRIPTION

Services form the middle layer of the Service Configuration Facility repository tree. Services are children of a scope (see scf_scope_create(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_create(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 service at any given time. The scf_service_create() function allocates and initializes a new scf_service_t bound to handle. The scf_service_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 specified 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_service_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. Otherwise, it returns -1.

Upon successful completion, scf_service_get_parent(), scf_scope_get_service(), scf_scope_add_service(), and scf_service_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_service_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 repository server (svc.configd(8)) 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.
