appendWithRetry()

void Vertica::UDFileOperator::appendWithRetry	(	const void *	buffer,
		size_t	size
	)

A wrapper around the append(). Attempt to write the specified data to disk. Retry in cases that didn't succeed in writing all data, but that stand a decent chance of succeeding on a retry. Throws on error.
