NAME

6       aio_return - get return status of asynchronous I/O operation
7

SYNOPSIS

9       #include <aio.h>
10
11       ssize_t aio_return(struct aiocb *aiocbp);

DESCRIPTION

16       The aio_return() function returns the final return status for the asyn‐
17       chronous I/O request with control block pointed to by aiocbp.
18
19       This function should be called only once for any given  request,  after
20       aio_error(3) returns something other than EINPROGRESS.
21

RETURN VALUE

23       If  the asynchronous I/O operation has completed, this function returns
24       the value that would have been returned in case of a synchronous  read,
25       write,  or fsync request.  Otherwise the return value is undefined.  On
26       error, the error value is returned.
27

ERRORS

29       EINVAL aiocbp does not point at a control block for an asynchronous I/O
30              request of which the return status has not been retrieved yet.
31
