DESCRIPTION
The aio_error() function
returns the error status for the asynchronous I/O request
with control block pointed to by aiocbp. (See aio(7) for a description of
the aiocb structure.)
RETURN VALUE
This function returns one of the following:
-
EINPROGRESS, if the request has not been completed yet.
-
ECANCELED, if the request was canceled.
-
0, if the request completed successfully.
-
A positive error number, if the asynchronous I/O operation failed. This is the same value that would have been stored in the
errnovariable in the case of a synchronous read(2), write(2), fsync(2), or fdatasync(2) call.
ERRORS
- EINVAL
-
aiocbpdoes not point at a control block for an asynchronous I/O request of which the return status (see aio_return(3)) has not been retrieved yet. - ENOSYS
-
aio_error() is not implemented.
