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	  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  indicating	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 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.
