64-Bit AIO

The Solaris operating environment provides a new set of interfaces for developers who want to do asynchronous I/O to large files. The following interfaces accept 64-bit AIO:

• aio_read64

• aio_write64

• lio_listio64

• aio_suspend64

• aio_error64

• aio_return64

The following interfaces exist, but are not supported:

• aio_fsync64

• aio_cancel64

These interfaces also work with KAIO. KAIO is the optimized path for doing I/O to raw files. When using the interfaces with KAIO to raw files, there is a significant performance improvement.

The Solaris operating environment supports another set of AIO interfaces that pre-dates POSIX. These interfaces have also been updated for large file support:

• aioread64

• aiowrite64
