NAME
     aio.h, aio - asynchronous input and output

SYNOPSIS
     #include 


DESCRIPTION
     The    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 can-
                        celed 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 notifi-
                        cation 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

                        is complete.


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