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_instance *inst,
    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);

 

DESCRIPTION

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.  

RETURN VALUES

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.  

ERRORS

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.
