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?

Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
