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.
