7.7. Closing an open directory

When we're done reading the directory, we need to close it. To do that, we will call the Close Directory API, closedir().

Here's the C and RPG prototypes for closedir():

      int closedir(DIR *dirp)                                

     D closedir        PR            10I 0 EXTPROC('closedir') 
     D  dirhandle                      *   VALUE               

Calling this API is quite simple, just pass it the variable that you received when you called opendir().

For example:

      c                   if        closedir(d) < 0
      c                   callp     EscErrno(errno)
      c                   endif
