aio_error - get error status of asynchronous I/O operation
Real-time library (librt, -lrt)
#include <aio.h> int aio_error(const struct aiocb *aiocbp);
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. > 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.
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.
