NAME
scf_handle_decode_fmri, scf_scope_to_fmri, scf_service_to_fmri, scf_instance_to_fmri, scf_pg_to_fmri, scf_property_to_fmri - convert
between objects and FMRIs in the Service Configuration Facility
SYNOPSIS
cc [ flag... ] file... -lscf [ library... ]
#include <libscf.h>
scf_handle_decode_fmri(scf_handle_t *handle, const char *fmri, scf_scope_t *scope, scf_service_t *service, scf_instance_t *instance,
scf_propertygroup_t *pg, scf_property_t *property, int flag);
ssize_t scf_scope_to_fmri(const scf_scope_t *object, char *buffer, size_t sz);
ssize_t scf_service_to_fmri(const scf_scope_t *object, char *buffer, size_t sz);
ssize_t scf_instance_to_fmri(const scf_scope_t *object, char *buffer, size_t sz);
ssize_t scf_pg_to_fmri(const scf_scope_t *object, char *buffer, size_t sz);
ssize_t scf_property_to_fmri(const scf_scope_t *object, char *buffer, size_t sz);
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() suc-
ceeds 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_prop-
erty_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_NO_RESOURCES
The server does not have adequate resources to complete the request.
SCF_ERROR_INVALID_ARGUMENT
The fmri argument is not a valid FMRI.
SCF_ERROR_CONSTRAINT_VIOLATED
The FMRI does not meet the restrictions requested in the flag argument.
SCF_ERROR_NOT_FOUND
The FMRI is well-formed but there is no object in the repository matching it.
SCF_ERROR_NOT_BOUND
The handle is not currently bound.
SCF_ERROR_CONNECTION_BROKEN
The connection to the repository was lost.
SCF_ERROR_HANDLE_MISMATCH
One or more of the entity handles was not derived from handle.
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
The object argument is not currently set.
SCF_ERROR_DELETED
The object argument refers to an object that has been deleted.
SCF_ERROR_NOT_BOUND
The handle is not currently bound.
SCF_ERROR_CONNECTION_BROKEN
The connection to the repository was lost.
The scf_error(3SCF) function can be used to retrieve the error value.
