|
|
541 | |
|
|
542 | =item aio_readdirx $pathname, $flags, $callback->($entries, $flags) |
|
|
543 | |
|
|
544 | Quite similar to C<aio_readdir>, but the C<$flags> argument allows to tune |
|
|
545 | behaviour and output format. In case of an error, C<$entries> will be |
|
|
546 | C<undef>. |
|
|
547 | |
|
|
548 | The flags are a combination of the following constants, ORed together (the |
|
|
549 | flags will also be passed to the callback, possibly modified): |
|
|
550 | |
|
|
551 | =over 4 |
|
|
552 | |
|
|
553 | =item AIO::READDIR_DENTS |
|
|
554 | |
|
|
555 | When this flag is off, then the callback gets an arrayref with of names |
|
|
556 | only (as with C<aio_readdir>), otherwise it gets an arrayref with |
|
|
557 | C<[$name, $inode, $type]> arrayrefs, each describing a single directory |
|
|
558 | entry in more detail. |
|
|
559 | |
|
|
560 | C<$name> is the name of the entry. |
|
|
561 | |
|
|
562 | C<$inode> is the inode number (which might not be exact on systems with 64 |
|
|
563 | bit inode numbers and 32 bit perls). On systems that do not deliver the |
|
|
564 | inode information, this will always be zero. |
|
|
565 | |
|
|
566 | C<$type> is one of the C<AIO::DT_xxx> constants: |
|
|
567 | |
|
|
568 | C<AIO::DT_UNKNOWN>, C<AIO::DT_FIFO>, C<AIO::DT_CHR>, C<AIO::DT_DIR>, |
|
|
569 | C<AIO::DT_BLK>, C<AIO::DT_REG>, C<AIO::DT_LNK>, C<AIO::DT_SOCK>, |
|
|
570 | C<AIO::DT_WHT>. |
|
|
571 | |
|
|
572 | C<AIO::DT_UNKNOWN> means just that: readdir does not know. If you need to |
|
|
573 | know, you have to run stat yourself. Also, for speed reasons, the C<$type> |
|
|
574 | scalars are read-only: you can not modify them. |
|
|
575 | |
|
|
576 | =item AIO::READDIR_DIRS_FIRST |
|
|
577 | |
|
|
578 | When this flag is set, then the names will be returned in an order where |
|
|
579 | likely directories come first. This is useful when you need to quickly |
|
|
580 | find directories, or you want to find all directories while avoiding to |
|
|
581 | stat() each entry. |
|
|
582 | |
|
|
583 | =item AIO::READDIR_STAT_ORDER |
|
|
584 | |
|
|
585 | When this flag is set, then the names will be returned in an order |
|
|
586 | suitable for stat()'ing each one. That is, when you plan to stat() |
|
|
587 | all files in the given directory, then the returned order will likely |
|
|
588 | be fastest. |
|
|
589 | |
|
|
590 | If both this flag and IO::READDIR_DIRS_FIRST are specified, then the |
|
|
591 | likely dirs come first, resulting in a less optimal stat order. |
|
|
592 | |
|
|
593 | =item AIO::READDIR_FOUND_UNKNOWN |
|
|
594 | |
|
|
595 | This flag should not be set when calling C<aio_readdirx>. Instead, it |
|
|
596 | is being set by C<aio_readdirx>, when any of the C<$type>'s found were |
|
|
597 | C<AIO::DT_UNKNOWN>. The absense of this flag therefore indicates that all |
|
|
598 | C<$type>'s are known, which can be used to speed up some algorithms. |
