Instances form the bottom layer of the Service Configuration Facility repository tree. An instance is the child of a service and has two sets of children: Property Groups

Snapshots

See smf(7) for information about instances.

An scf_instance_t is an opaque handle that can be set to a single instance at any given time. The scf_instance_create() function allocates and initializes a new scf_instance_t bound to handle. The scf_instance_destroy() function destroys and frees inst.

The scf_instance_handle() function retrieves the handle to which inst is bound.

The scf_inst_get_parent() function sets svc to the service that is the parent of inst.

The scf_instance_get_name() function retrieves the name of the instance to which inst is set.

The scf_service_get_instance() function sets inst to the child instance of the service svc specified by name.

The scf_service_add_instance() function sets inst to a new child instance of the service svc specified by name.

The scf_instance_delete() function deletes the instance to which inst is set, as well all of the children of the instance.

Upon successful completion, scf_instance_create() returns a new scf_instance_t. Otherwise it returns NULL.

Upon successful completion, scf_instance_handle() returns the handle to which inst is bound. Otherwise, it returns NULL.

Upon successful completion, scf_instance_get_name() returns the length of the string written, not including the terminating null character. Otherwise it returns -1.

Upon successful completion, scf_instance_get_parent(), scf_service_get_instance(), scf_service_add_instance(), and scf_instance_delete() functions return 0. Otherwise, they return -1.

Instance names are of the form:

[domain,]identifier

where domain is either a stock ticker symbol such as SUNW or a Java-style reversed domain name such as com.sun. Identifiers begin with a letter or underscore and contain only letters, digits, underscores, and dashes.
