Имя (Name)

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

Синопсис (Synopsis)

#include <dirent.h>

void rewinddir(DIR *dirp);

Описание (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.

Возвращаемое значение (Return value)

The rewinddir() function shall not return a value.
