Hello

If you look at the opendir(3) manpage, you will see that perl's opendir, readdir and closedir are handled directly by their C counterparts. The DIR * data type is defined I believe in dirent.h or in sys/types.h.

I believe implementing opendir, readdir and closedir are straightforward in XS given that this is their calling syntax:

DIR *opendir(const char *name);
int closedir(DIR *dir);
struct dirent *readdir(DIR *dir);

Did I answer the question?
