Return a null terminated (C‐style) string describing the default file‐system path of the (expected) root of the Zoneinfo Database time‐zone information files. The returned string will be the current value of the `BDE_ZONEINFO_ROOT_PATH` environment variable, if set, or else one of a (priority ordered) sequence of (platform‐specific) standard directories, if one of those directories exists and contains a sub‐set of expected files, and the current directory, otherwise. The behavior is undefined if the returned address is dereferenced after a subsequent call to the `putenv` POSIX function to set the `BDE_ZONEINFO_ROOT_PATH` environment variable.
