eio_readdir — Reads through a whole directory
Reads through a whole directory(via the opendir, readdir and
closedir system calls) and returns either the names or an array in
result argument of callback
function, depending on the flags argument.
pathDirectory path.
flagsCombination of EIO_READDIR_* constants.
priThe request priority: EIO_PRI_DEFAULT, EIO_PRI_MIN, EIO_PRI_MAX, or null.
If null passed, pri internally is set to
EIO_PRI_DEFAULT.
callback
callback function is called when the request is done.
It should match the following prototype:
void callback(mixed $data, int $result[, resource $req]);datais custom data passed to the request.
resultrequest-specific result value; basically, the value returned by corresponding system call.
reqis optional request resource which can be used with functions like eio_get_last_error().
data
Arbitrary variable passed to callback.
eio_readdir() returns request resource on success, başarısızlık durumunda false döner.
Sets result argument of
callback function according to
flags:
EIO_READDIR_DENTS
(int)
'names' - array of directory names
'dents' - array of struct
eio_dirent-like arrays having the following keys each:
'name' - the directory name;
'type' - one of EIO_DT_*
constants;
'inode' - the inode number, if available, otherwise
unspecified;
EIO_READDIR_DIRS_FIRST
(int)
EIO_READDIR_STAT_ORDER
(int)
stat'ing each one. When planning to
stat() all files in the given directory, the
returned order will likely be
fastest.
