int aio_write64(struct aiocb *aiocbp);
DESCRIPTIONThis function is similar to the aio_write function. The only difference is that on 32 bit machines the file descriptor should be opened in the large file mode. Internally aio_write64 uses functionality equivalent to lseek64 to position the file descriptor correctly for the writing, as opposed to lseek functionality used in aio_write.
When the sources are compiled with _FILE_OFFSET_BITS == 64 , this function is available under the name aio_write and so transparently replaces the interface for small files on 32 bit machines.
