aio_return(3c)

Standard C Library Functions                                    aio_return(3C)



NAME
       aio_return - retrieve return status of an asynchronous I/O operation

SYNOPSIS
       #include <aio.h>

       ssize_t aio_return(struct aiocb *aiocbp);

DESCRIPTION
       The aio_return() function returns the return status associated with the
       aiocb structure referenced by the aiocbp argument.  The  return  status
       for  an  asynchronous I/O operation is the value that would be returned
       by the corresponding read(2), write(2), or fsync(3C) function call.  If
       the  error  status  for the operation is equal to EINPROGRESS, then the
       return status for the operation is undefined. The aio_return() function
       may  be  called  exactly  once to retrieve the return status of a given
       asynchronous operation; thereafter, if the same aiocb structure is used
       in  a  call to aio_return() or aio_error(3C), an error may be returned.
       When the aiocb structure referred  to  by  aiocbp  is  used  to  submit
       another  asynchronous  operation, then aio_return() may be successfully
       used to retrieve the return status of that operation.

RETURN VALUES
       If the asynchronous I/O operation has completed, then the  return  sta‐
       tus, as described for read(2), write(2), and fsync(3C), is returned. If
       the asynchronous I/O operation has not yet completed,  the  results  of
       aio_return() are undefined.

ERRORS
       The aio_return() function will fail if:

       EINVAL    The  aiocbp argument does not refer to an asynchronous opera‐
                 tion whose return status has not yet been retrieved.


       ENOSYS    The aio_return() function is not supported by the system.


USAGE
       The aio_return() function has a transitional interface for 64-bit  file
       offsets. See lf64(7).
