NAME LIBRARY SYNOPSIS DESCRIPTION RETURN VALUE ERRORS ATTRIBUTES STANDARDS HISTORY EXAMPLES SEE ALSO

NAME

aio_error − get error status of asynchronous I/O operation

LIBRARY

Real-time library (librt, −lrt)

SYNOPSIS

#include <aio.h>

int aio_error(const struct aiocb *aiocbp);

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.
	> 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.
