#include <aio.h>
DESCRIPTION
The <aio.h> header defines the aiocb structure which includes the fol‐
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 signal number and value
int aio_lio_opcode operation to be performed
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 complete.
AIO_CANCELED A return value indicating that all requested
operations 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(3RT) element operation option
indicating that no transfer is requested.
LIO_NOWAIT A lio_listio() synchronization operation indi‐
cating that the calling thread is to continue
execution while the lio_listio() operation is
being performed, and no notification is given
when the operation is complete.
LIO_READ A lio_listio() element operation option
requesting a read.
LIO_WAIT A lio_listio() synchronization operation indi‐
cating that the calling thread is to suspend
until the lio_listio() operation is complete.
LIO_WRITE A lio_listio() element operation option
requesting a write.
