closedir, wclosedir 

Header File
dirent.h
Category
Directory Control Routines
Prototype
void closedir(DIR *dirp);
void wclosedir(wDIR *dirp);
Description
Closes a directory stream.
closedir is available on POSIX-compliant UNIX systems.
The closedir function closes the directory stream dirp, which must have been opened by a previous call to opendir. After the stream is closed, dirp no longer points to a valid directory stream.
wclosedir is the Unicode version of closedir.
Return Value
If closedir is successful, it returns 0. Otherwise, closedir returns -1 and sets the global variable errno to  

opendir, wopendir

Directory Control Routines
Prototype
DIR *opendir(const char *dirname);
wDIR *wopendir(const wchar_t *dirname);
Description
Opens a directory stream for reading.
opendir is available on POSIX-compliant UNIX systems.
The opendir function opens a directory stream for reading. The name of the directory to read is dirname. The stream is set to read the first entry in the directory.
A directory stream is represented by the DIR structure, defined in dirent.h. This structure contains no user-accessible fields. Multiple directory streams can be opened and read simultaneously. Directory entries can be created or deleted while a directory stream is being... more 

readdir, wreaddir 

Header File
dirent.h
Category
Directory Control Routines
Prototype
struct dirent *readdir(DIR *dirp);
struct wdirent *wreaddir(wDIR *dirp)
Description
Reads the current entry from a directory stream.
readdir is available on POSIX-compliant UNIX systems.
The readdir function reads the current directory entry in the directory stream pointed to by dirp. The directory stream is advanced to the next entry.
The readdir function returns a pointer to a dirent structure that is overwritten by each call to the function on the same directory stream. The structure is not overwritten by a readdir call on a different directory stream.
The dirent structure corresponds to... more 

rewinddir, wrewinddir 

Header File
dirent.h
Category
Directory Control Routines
Prototype
void rewinddir(DIR *dirp);
void wrewinddir(wDIR *dirp);
Description
Resets a directory stream to the first entry.
rewinddir is available on POSIX-compliant UNIX systems.
The rewinddir function repositions the directory stream dirp at the first entry in the directory. It also ensures that the directory stream accurately reflects any directory entries that might have been created or deleted since the last opendir or rewinddir on that directory stream.
wrewinddir is the Unicode version of rewinddir.
Return Value
None.
