- * A wrapper for mkdir(2).

  * \param path Name of the directory to create.
- * \param mode The permissions to use.

- * \return Standard.
+ * This function passes the fixed mode value 0777 to mkdir(3) (which consults
+ * the file creation mask and restricts this value).
+ *
+ * \return Zero if the directory already existed, one if the directory has been
+ * created, negative error code if the mkdir(3) call failed for any reason
+ * other than EEXIST.
