int aio_read64(struct aiocb *aiocbp);

Overview

This function is similar to the aio_read function. The only difference is that on 32 bit machines, the file descriptor should be opened in the large file mode. Internally, aio_read64 uses functionality equivalent to lseek64 to position the file descriptor correctly for the reading, as opposed to lseek functionality used in aio_read.

When the sources are compiled with _FILE_OFFSET_BITS == 64, this function is available under the name aio_read and so transparently replaces the interface for small files on 32 bit machines.
