BloombergLP::baltzo::DataFileLoader::configureRootPathIfPlausible

Set, to the specified path, the root of the file‐system directory hierarchy from which this loader will read Zoneinfo binary time‐zone information files. Return 0 on success, and a non‐zero value (without no effect) if path is not a directory that appears to contain valid Zoneinfo data, as determined by calling isPlausibleZoneinfoRootPath on path.
