       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_lis-
			  tio() 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()  opera-
			  tion is complete.

       LIO_WRITE	  A lio_listio() element operation option requesting a write.
