NAME

       rewinddir — reset the position of a directory stream to the beginning of a directory

SYNOPSIS

       #include <dirent.h>

       void rewinddir(DIR *dirp);

DESCRIPTION

       The  rewinddir()  function  shall reset the position of the directory stream to which dirp
       refers to the beginning of the directory. It shall also  cause  the  directory  stream  to
       refer  to  the  current state of the corresponding directory, as a call to opendir() would
       have done. If dirp does not refer to a directory stream, the effect is undefined.

       After a call to the fork() function, either  the  parent  or  child  (but  not  both)  may
       continue  processing  the directory stream using readdir(), rewinddir(), or seekdir().  If
       both the parent and child processes use these functions, the result is undefined.

RETURN VALUE

       The rewinddir() function shall not return a value.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       The rewinddir() function should be used in  conjunction  with  opendir(),  readdir(),  and
       closedir()  to  examine  the  contents  of  the  directory. This method is recommended for
       portability.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
