|Default constructor. |
|ACE_Dirent (const ACE_TCHAR *dirname)|
|Constructor calls <opendir>. |
|int||open (const ACE_TCHAR *filename)|
|Destructor calls <closedir>. |
|Closes the directory stream and frees the <ACE_DIR> structure. |
|ACE_DIRENT *||read (void)|
|int||read (struct ACE_DIRENT *entry, struct ACE_DIRENT **result)|
|void||seek (long loc)|
|Pointer to the directory stream. |
|ACE_INLINE ACE_Dirent::ACE_Dirent||(||const ACE_TCHAR *||dirname||)||
Constructor calls <opendir>.
Destructor calls <closedir>.
|ACE_INLINE void ACE_Dirent::close||(||void||)|
Closes the directory stream and frees the <ACE_DIR> structure.
|ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE int ACE_Dirent::open||(||const ACE_TCHAR *||filename||)|
Opens the directory named by filename and associates a directory stream with it.
|ACE_INLINE int ACE_Dirent::read||(||struct ACE_DIRENT *||entry,|
|struct ACE_DIRENT **||result|
Has the equivalent functionality as <readdir> except that an <entry> and <result> buffer must be supplied by the caller to store the result.
|ACE_INLINE ACE_DIRENT * ACE_Dirent::read||(||void||)|
Returns a pointer to a structure representing the directory entry at the current position in the directory stream to which dirp refers, and positions the directory stream at the next entry, except on read-only filesystems. It returns a NULL pointer upon reaching the end of the directory stream, or upon detecting an invalid location in the directory. <readdir> shall not return directory entries containing empty names. It is unspecified whether entries are returned for dot or dot-dot. The pointer returned by <readdir> points to data that may be overwritten by another call to <readdir> on the same directory stream. This data shall not be overwritten by another call to <readdir> on a different directory stream. <readdir> may buffer several directory entries per actual read operation; <readdir> marks for update the st_atime field of the directory each time the directory is actually read.
|ACE_INLINE void ACE_Dirent::rewind||(||void||)|
Resets the position of the directory stream 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> would.
|ACE_INLINE void ACE_Dirent::seek||(||long||loc||)|
Sets the position of the next <readdir> operation on the directory stream. The new position reverts to the position associated with the directory stream at the time the <telldir> operation that provides loc was performed. Values returned by <telldir> are good only for the lifetime of the <ACE_DIR> pointer from which they are derived. If the directory is closed and then reopened, the <telldir> value may be invalidated due to undetected directory compaction. It is safe to use a previous <telldir> value immediately after a call to <opendir> and before any calls to readdir.
|ACE_INLINE long ACE_Dirent::tell||(||void||)|
Returns the current location associated with the directory stream.
