aio_error3
Get error status of asynchronous i/o operation
Usage
#include <aio.h>
int aio_error(const struct aiocb *aiocbp);
Library
Real-time library (librt, -lrt)
Overview
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.
- >
0 -
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.
Errors
- EINVAL
-
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 retrieved yet.
- ENOSYS
-
aio_error() is not implemented.
