lowing members:
int aio_fildes file descriptor
off_t aio_offset file offset
volatile void* aio_buf location of buffer
size_t aio_nbytes length of transfer
int aio_reqprio request priority offset
struct sigevent aio_sigevent notification type
int aio_lio_opcode listio operation
This header also includes the following constants:
AIO_ALLDONE A return value indicating that none of the requested
operations could be canceled since they are already

AIO_CANCELED A return value indicating that all requested opera‐
tions have been canceled.
AIO_NOTCANCELED A return value indicating that some of the requested
operations could not be canceled since they are in
progress.
LIO_NOP A lio_listio(3C) element operation option indicating
that no transfer is requested.
LIO_NOWAIT A lio_listio() synchronization operation indicating
that the calling thread is to continue execution
while the lio_listio() operation is being performed,
and notification is to be given when the operation
is complete.
LIO_READ A lio_listio() element operation option requesting a
read.
