REWINDDIR(3C) Standard C Library Functions REWINDDIR(3C)

NAME

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

SYNOPSIS

#include <sys/types.h>
#include <dirent.h>

void rewinddir(DIR *dirp);

DESCRIPTION

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.

RETURN VALUES

The rewinddir() function does not return a value.

ERRORS

No errors are defined.

USAGE

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.
