NAME
rewinddir - reset the position of a directory stream to the beginning
of a directory
SYNOPSIS
#include <dirent.h>
void rewinddir(DIR *dirp);
DESCRIPTION
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.
ERRORS
No errors are defined.
The following sections are informative.
EXAMPLES
None.
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.
RATIONALE
None.
FUTURE DIRECTIONS
None.
