Any number of the entity handles can be \fINULL\fR. The validation and decoding of the FMRI are determined by the \fIflags\fR argument and by those arguments that are \fINULL\fR. .sp .LP If \fIflags\fR == 0, any FMRI is accepted as long as it is well-formed and exists in the repository. .sp .LP If \fBSCF_DECODE_FMRI_EXACT\fR is set in \fIflags\fR, the last part of the FMRI must match the last non-null entity handle. For example, if property is \fINULL\fR and \fIpg\fR is non-null, the FMRI must be a property group FMRI. .sp .LP If \fBSCF_DECODE_FMRI_TRUNCATE\fR is set in \fIflags\fR, 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 \fINULL\fR, \fIpg\fR is non-null, and a property FMRI is passed in, \fBscf_handle_decode_fmri()\fR succeeds as long as the property group exists, even if the referenced property does not exist. .sp .LP If \fBSCF_DECODE_FMRI_REQUIRE_INSTANCE\fR (or \fBSCF_DECODE_FMRI_REQUIRE_NO_INSTANCE\fR) is set in \fIflags\fR, then the FMRI must (or must not) specify an instance. .sp .LP If an error occurs, all of the entity handles that were passed to the function are reset. .sp .LP The \fBscf_scope_to_fmri()\fR, \fBscf_service_to_fmri()\fR, \fBscf_instance_to_fmri()\fR, \fBscf_pg_to_fmri()\fR, and \fBscf_property_to_fmri()\fR functions convert an entity handle to an FMRI. .SH RETURN VALUES .sp .LP Upon successful completion, \fBscf_handle_decode_fmri()\fR returns 0. Otherwise, it returns -1. .sp .LP Upon successful completion, \fBscf_scope_to_fmri()\fR, \fBscf_service_to_fmri()\fR, \fBscf_instance_to_fmri()\fR, \fBscf_pg_to_fmri()\fR, and \fBscf_property_to_fmri()\fR return the length of the FMRI. The buffer will be null-terminated if \fIsz\fR > 0, similar to strlcpy(3C). Otherwise, they return -1 and the contents of buffer are undefined. .SH ERRORS .sp .LP The \fBscf_handle_decode_fmri()\fR function will fail if: .sp .ne 2 .mk .na \fB\fBSCF_ERROR_BACKEND_ACCESS\fR\fR .ad .sp .6 .RS 4n The storage mechanism that the repository server (\fBsvc.configd\fR(1M)) chose for the operation denied access. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_CONNECTION_BROKEN\fR\fR .ad .sp .6 .RS 4n The connection to the repository was lost. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_CONSTRAINT_VIOLATED\fR\fR .ad .sp .6 .RS 4n The FMRI does not meet the restrictions requested in the \fIflags\fR argument. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_DELETED\fR\fR .ad .sp .6 .RS 4n The object argument refers to an object that has been deleted. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_HANDLE_MISMATCH\fR\fR .ad .sp .6 .RS 4n One or more of the entity handles was not derived from handle. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_INTERNAL\fR\fR .ad .sp .6 .RS 4n An internal error occurred. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_INVALID_ARGUMENT\fR\fR .ad .sp .6 .RS 4n The \fIfmri\fR argument is not a valid FMRI. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_NO_RESOURCES\fR\fR .ad .sp .6 .RS 4n The server does not have adequate resources to complete the request. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_NOT_BOUND\fR\fR .ad .sp .6 .RS 4n The handle is not currently bound. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_NOT_FOUND\fR\fR .ad .sp .6 .RS 4n The FMRI is well-formed but there is no object in the repository matching it. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_NOT_SET\fR\fR .ad .sp .6 .RS 4n Cannot use unset value. .RE .sp .LP The \fBscf_scope_to_fmri()\fR, \fBscf_service_to_fmri()\fR, \fBscf_instance_to_fmri()\fR, \fBscf_pg_to_fmri()\fR, and \fBscf_property_to_fmri()\fR functions will fail if: .sp .ne 2 .mk .na \fB\fBSCF_ERROR_NOT_SET\fR\fR .ad .sp .6 .RS 4n The \fIobject\fR argument is not currently set. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_DELETED\fR\fR .ad .sp .6 .RS 4n The object argument refers to an object that has been deleted. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_NOT_BOUND\fR\fR .ad .sp .6 .RS 4n The handle is not currently bound. .RE .sp .ne 2 .mk .na \fB\fBSCF_ERROR_CONNECTION_BROKEN\fR\fR .ad .sp .6 .RS 4n The connection to the repository was lost. .RE .sp .LP The \fBscf_error\fR(3SCF) function can be used to retrieve the error value. .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS tab() box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
