REWINDDIR(3C) Standard C Library Functions REWINDDIR(3C)
rewinddir - reset position of directory stream to the beginning of a
directory
#include <sys/types.h>
#include <dirent.h>
void rewinddir(DIR *dirp);
The rewinddir() function resets the position of the directory stream
to which dirp refers to the beginning of the directory. It also
causes the directory stream to refer to the current state of the
corresponding directory, as a call to opendir(3C) would have done.
If dirp does not refer to a directory stream, the effect is
undefined.
After a call to the fork(2) function, either the parent or child (but
not both) may continue processing the directory stream using
readdir(3C), rewinddir() or seekdir(3C). If both the parent and child
processes use these functions, the result is undefined.
The rewinddir() function does not return a value.
No errors are defined.
The rewinddir() function should be used in conjunction with
opendir(), readdir(), and closedir(3C) to examine the contents of the
directory. This method is recommended for portability.

RETURN VALUES
The rewinddir() function does not return a value.
