Reads through a whole directory

resource **eio_readdir** string $path int $flags int $pri callable $callback string $data

Reads through a whole directory(via the , and system calls) and returns either the names or an array in argument of function, depending on the argument. opendir``readdir``closedir``result``callback``flags

pathDirectory path.

flags Combination of constants. EIO_READDIR_*

pri``callback``data Arbitrary variable passed to . callback

returns request resource on success,return.falseforfailure.

Sets argument of function according to : eio_readdir``result``callback``flags

EIO_READDIR_DENTS``int flag. If specified, the result argument of the callback becomes an array with the following keys: - array of directory names - array of -like arrays having the following keys each: - the directory name; - one of constants; - the inode number, if available, otherwise unspecified; eio_readdir``'names'``'dents'``struct eio_dirent``'name'``'type'*EIO_DT_**'inode'

EIO_READDIR_DIRS_FIRST``intWhen this flag is specified, the names will be returned in an order where likely directories come first, in optimal stat order.

EIO_READDIR_STAT_ORDER``int When this flag is specified, then the names will be returned in an order suitable for 'ing each one. When planning to all files in the given directory, the returned order will likely be fastest. stat``stat
