aio_error - get error status of asynchronous I/O operation
int aio_error(const struct aiocb *aiocbp);
Link with -lrt.
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.)
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 errno variable in
the case of a synchronous read(2), write(2),
fsync(2), or fdatasync(2) call.
The aio_error() function is available since glibc 2.1.
For an explanation of the terms used in this section, see attributes(7).
- aiocbp does not point at a control block for an asynchronous I/O
request of which the return status (see aio_return(3)) has not been
- aio_error() is not implemented.
