NAME

       aio_return() - return status of an asynchronous I/O operation

SYNOPSIS

DESCRIPTION

       The  function returns the return status associated with the structure referenced by the aiocbp argument.  The return value for an asynchro-
       nous I/O operation is the value that would be set by the corresponding or operation.  If the operation has been queued but  not	completed,
       returns and is set to A successful call frees all kernel resources associated with the calls referenced by aiocbp.

       To use this function, link in the realtime library by specifying on the compiler or linker command line.

RETURN VALUE

       If the is invalid or if no asynchronous I/O operation is enqueued for the returns and is set to indicate the error.  Otherwise, returns the
       error status of the referenced See aio_read(2), read(2), aio_write(2), write(2), aio_fsync(2),  fsync(2)  and  lio_listio(2)  for  relevant
       error values.

ERRORS

       If detects one of the following error conditions, is set to the indicated value:

	      [EINVAL]	     The aiocbp is not a valid address within the process virtual address space.

	      [EINVAL]	     There was no asynchronous I/O operation enqueued for the referenced

EXAMPLE

       The following code sequence illustrates using to retrieve the error status of an operation and free the for future re-use.
