Scopes are the top level of the Service Configuration Facility’s repository tree. The children of a scope are services (see scf_service_create(3SCF) ) and can be walked using scf_iter_scope_services(3SCF) .

There is a distinguished scope with the name SCF_SCOPE_LOCAL that is the root for all available services on the local machine. In the current implementation, there are no other scopes.

An scf_scope_t is an opaque handle that can be set to a single scope at any given time. The scf_scope_create() function allocates a new scf_scope_t bound to handle. The scf_scope_destroy() function destroys and frees sc.

The scf_scope_handle() function retrieves the handle to which sc is bound.

The scf_scope_get_name() function retrieves the name of the scope to which sc is set.

The scf_handle_get_scope() function sets out to the scope specified by name for the repository handle specified by handle. The scf_iter_handle_scopes(3SCF) and scf_iter_next_scope(3SCF) calls can be used to iterate through all available scopes.

Return Values

Upon successful completion, scf_scope_create() returns a new scf_scope_t. Otherwise, it returns NULL.

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

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

Upon successful completion, scf_handle_get_scope() returns 0. Otherwise, it returns -1.


The scf_scope_create() function will fail if:


The value of the handle argument is NULL.


There is not enough memory to allocate an scf_scope_t.


The server does not have adequate resources for a new scope handle.

The scf_scope_handle() function will fail if:


The handle associated with sc has been destroyed.

The scf_scope_get_name() function will fail if:


The scope is not set.


The handle is not bound.


The connection to the repository was lost.

The scf_handle_get_scope() function will fail if:


No scope named name was found.


The name argument is not a valid scope name.


The handle is not bound.


The connection to the repository was lost.


The value of the out argument is not derived from handle.

The scf_error(3SCF) function can be used to retrieve the error value.
