ACE_Dirent::ACE_Dirent | ( | void | ) | [inline] |
Default constructor.
ACE_Dirent::ACE_Dirent | ( | const ACE_TCHAR * | dirname | ) | [inline, explicit] |
Constructor calls opendir()
.
ACE_Dirent::~ACE_Dirent | ( | void | ) | [inline] |
Destructor calls closedir()
.
void ACE_Dirent::close | ( | void | ) | [inline] |
Closes the directory stream and frees the ACE_DIR structure.
int ACE_Dirent::open | ( | const ACE_TCHAR * | filename | ) | [inline] |
Opens the directory named by filename and associates a directory stream with it.
int ACE_Dirent::read | ( | struct ACE_DIRENT * | entry, | |
struct ACE_DIRENT ** | result | |||
) | [inline] |
Has the equivalent functionality as <readdir> except that an entry and result buffer must be supplied by the caller to store the result.
ACE_DIRENT * ACE_Dirent::read | ( | void | ) | [inline] |
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.
void ACE_Dirent::rewind | ( | void | ) | [inline] |
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.
void ACE_Dirent::seek | ( | long | loc | ) | [inline] |
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.
long ACE_Dirent::tell | ( | void | ) | [inline] |
Returns the current location associated with the directory stream.
ACE_DIR* ACE_Dirent::dirp_ [private] |
Pointer to the directory stream.
