NAME
aio.h, aio - asynchronous input and output
SYNOPSIS

#include <aio.h>
DESCRIPTION

The <aio.h> header defines the aiocb structure which includes the following 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 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(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.

LIO_WAIT

A lio_listio() synchronization operation indicating 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.
