368 | aio_statvfs $fh_or_path, $callback->($statvfs) |
|
|
369 | Works like the POSIX "statvfs" or "fstatvfs" syscalls, depending on |
|
|
370 | whether a file handle or path was passed. |
|
|
371 | |
|
|
372 | On success, the callback is passed a hash reference with the |
|
|
373 | following members: "bsize", "frsize", "blocks", "bfree", "bavail", |
|
|
374 | "files", "ffree", "favail", "fsid", "flag" and "namemax". On |
|
|
375 | failure, "undef" is passed. |
|
|
376 | |
|
|
377 | The following POSIX IO::AIO::ST_* constants are defined: "ST_RDONLY" |
|
|
378 | and "ST_NOSUID". |
|
|
379 | |
|
|
380 | The following non-POSIX IO::AIO::ST_* flag masks are defined to |
|
|
381 | their correct value when available, or to 0 on systems that do not |
|
|
382 | support them: "ST_NODEV", "ST_NOEXEC", "ST_SYNCHRONOUS", |
|
|
383 | "ST_MANDLOCK", "ST_WRITE", "ST_APPEND", "ST_IMMUTABLE", |
|
|
384 | "ST_NOATIME", "ST_NODIRATIME" and "ST_RELATIME". |

386 | Example: stat "/wd" and dump out the data if successful. |
