The scf_handle_decode_fmri() function decodes an FMRI string into a set of repository entries. Any number of the entity handles can be NULL. The validation and decoding of the FMRI are determined by the flags argument and by those arguments that are NULL.
If flags == 0, any FMRI is accepted as long as it is well-formed and exists in the repository.
If SCF_DECODE_FMRI_EXACT is set in flags, the last part of the FMRI must match the last non-null entity handle. For example, if property is NULL and pg is non-null, the FMRI must be a property group FMRI.
If SCF_DECODE_FMRI_TRUNCATE is set in flags, there is no check for the existence of any objects specified in the FMRI that follow the last non-null entity handle. For example, if property is NULL, pg is non-null, and a property FMRI is passed in, scf_handle_decode_fmri() succeeds as long as the property group exists, even if the referenced property does not exist.
If SCF_DECODE_FMRI_REQUIRE_INSTANCE (or SCF_FMRI_REQUIRE_NO_INSTANCE) is set in flags, then the FMRI must (or must not) specify an instance.
If an error occurs, all of the entity handles that were passed to the function are reset.
The scf_scope_to_fmri(), scf_service_to_fmri(), scf_instance_to_fmri(), scf_pg_to_fmri(), and scf_property_to_fmri() functions convert an entity handle to an FMRI.
Upon successful completion, scf_handle_decode_fmri() returns 0. Otherwise, it returns -1.
Upon successful completion, scf_scope_to_fmri(), scf_service_to_fmri(), scf_instance_to_fmri(), scf_pg_to_fmri(), and scf_property_to_fmri() return the length of the FMRI. The buffer will be null-terminated if sz > 0, similar to strlcpy(3C). Otherwise, they return -1 and the contents of buffer are undefined.
The scf_handle_decode_fmri() function will fail if:
SCF_ERROR_BACKEND_ACCESS
SCF_ERROR_CONNECTION_BROKEN
SCF_ERROR_CONSTRAINT_VIOLATED
SCF_ERROR_DELETED
SCF_ERROR_HANDLE_MISMATCH
SCF_ERROR_INTERNAL
SCF_ERROR_INVALID_ARGUMENT
SCF_ERROR_NO_RESOURCES
SCF_ERROR_NOT_BOUND
SCF_ERROR_NOT_FOUND
SCF_ERROR_NOT_SET
The scf_scope_to_fmri(), scf_service_to_fmri(), scf_instance_to_fmri(), scf_pg_to_fmri(), and scf_property_to_fmri() functions will fail if:
SCF_ERROR_NOT_SET
SCF_ERROR_DELETED
SCF_ERROR_NOT_BOUND
SCF_ERROR_CONNECTION_BROKEN
The scf_error(3SCF) function can be used to retrieve the error value.
