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.
