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

  #include <dirent.h>
  void rewinddir(DIR *dirp);

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.

The /rewinddir/() function shall not return a value.

No errors are defined.

The following sections are informative.

None.

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.

None.

None.
