The template property functions locate and give access to metadata about properties. They require that the template for the property group containing the property has already been located by one of the scf_tmpl_pg_create(3SCF) suite of functions.
Once retrieved, the scf_prop_tmpl_t can be explored using the scf_tmpl_prop_name(3SCF) suite of functions.
Before calling scf_tmpl_get_by_prop() or scf_tmpl_iter_props(), the scf_prop_tmpl_t must be allocated by scf_tmpl_prop_create. The scf_prop_tmpl_t can be reset to contain no template information with scf_tmpl_prop_reset(), so that it can be used to start an iteration from scratch. All associated memory can be freed with scf_tmpl_prop_destroy(). The scf_error() function is not modified by this call.
The scf_tmpl_get_by_prop() function locates template data about the property name specified.
The scf_tmpl_iter_props() function iterates across all property templates defined in the specified property group template.
The iterator state for scf_tmpl_iter_props() is stored on the property template data structure. The data structure should be allocated with scf_tmpl_prop_create(), and to continue the iteration the previously returned structure should be passed in as an argument.
The scf_tmpl_get_by_prop() function returns -1 on failure and 0 on success.
The scf_tmpl_iter_props() function returns 0 for successful iteration to the next item, 1 for iteration successfully reaching its end, and —1 on error.
The scf_tmpl_get_by_prop() and scf_tmpl_iter_props() functions will fail if:
The storage mechanism that the repository server (svc.configd(8)) chose for the operation denied access.
The connection to the repository was lost.
The instance or its template property group has been deleted.
The handle passed in has been destroyed.
An internal error occurred.
One of the arguments is invalid.
There is not enough memory to populate the scf_prop_tmpl_t.
The server does not have adequate resources to complete the request.
The handle is not currently bound.
The scf_tmpl_get_by_prop() function will fail if:
Template object matching property doesn't exist in the repository.
Matching template object is the wrong type in the repository.
The template could not be read due to access restrictions.
The template data is invalid.
The scf_tmpl_prop_create() function will fail if:
The handle argument is NULL.
There is no memory available.
