NAME
aio_error - get error status of asynchronous I/O operationSYNOPSIS
#include <aio.h>int aio_error(const struct aiocb *aiocbp);
Link with -lrt.
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 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.
