Before the xfnts_start method attempts to start the X Font Server, it calls svc_validate() to verify that a correct configuration is in place to support the xfs daemon.
rc = svc_validate(scds_handle);
if (rc != 0) {
scds_syslog(LOG_ERR,
"Failed to validate configuration.");
return (rc);
}
See xfnts_validate Method for details.
