File and Path Function
DIR *opendir(const char *dirname);
Internationalization (I18n) Function Overview
The opendir function opens and returns a directory stream for reading the directory whose filename is dirname.
In the event of an error, opendir returns NULL and sets the global
errno variable with the error value.
I18n Issues
On ANSI UTF-16 platforms, use a conversion function to convert the
wide-character string to a multibyte-character string and then call opendir.
See Pathnames for a discussion of path and filename considerations in
an internationalized application.

*If you're already using the recommended function, see I18n Issues for other reasons why Globalyzer is detecting the function.
