File and Path Function Internationalization (I18n) Function OverviewThe pathconf is the requested value.
A value of -1 is returned to indicate that the implementation does not
impose a limit, and in case of an error. In the former case, the global variable errno
is not set, while in the latter case, errno is set to indicate the cause of the problem.
Therefore, the only way to use this function robustly is to store 0 into
errno just before calling pathconf .
I18n IssuesOn ANSI UTF-16 platforms, use a conversion function to convert the
wide-character string to a multibyte-character string and then call See Pathnames for a discussion of path and filename considerations in an internationalized application. Recommended Replacements*
