rewinddir - Man Page

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


This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.


#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.

Return Value

The rewinddir() function shall not return a value.


No errors are defined.

The following sections are informative.



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.
