SYNOPSIS
     #include 


DESCRIPTION
     The    header  defines  the  aiocb  structure   which
     includes the following members:

       int               aiofildes       file descriptor
       offt             aiooffset       file offset
       volatile void*    aiobuf          location of buffer
       sizet            aionbytes       length of transfer
       int               aioreqprio      request priority offset
       struct sigevent   aiosigevent     notification type
       int               aiolioopcode   listio operation



     This header also includes the following constants:

     AIOALDONE        A return value indicating  that  none  of
                        the  requested  operations  could be can-
                        celed since they are already complete.


     AIOCANCELED       A  return  value  indicating   that   all
                        requested operations have been canceled.


     AIONOTCANCELED    A return value indicating  that  some  of
                        the  requested  operations  could  not be
                        canceled since they are in progress.


     LIONOP            A liolistio(3C) element operation option
                        indicating that no transfer is requested.


     LIONOWAIT         A liolistio() synchronization  operation
                        indicating  that the calling thread is to
                        continue execution while the liolistio()
                        operation is being performed, and notifi-
                        cation is to be given when the  operation
                        is complete.


     LIOREAD           A liolistio() element  operation  option
                        requesting a read.

     LIOWAIT           A liolistio() synchronization  operation

                        is complete.


     LIOWRITE          A liolistio() element  operation  option
                        requesting a write.
