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.|
|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.|
|aio_error() is not implemented.|
The aio_error() function is available since glibc 2.1.
