const char* @53::readTmpFile	(	bistream &	imageTmp,
		JigdoDescVec &	filesTmp,
		const JigdoDescVec &	files
	)			[static]

Read data from end of temporary file imageTmp, output it to filesTmp.

Next, compare it to template data in "files". If tmp file is OK for re-using return NULL - this means that the DESC entries match *exactly* - the only difference allowed is MatchedFile turning into WrittenFile. Otherwise, return a pointer to an error message describing the reason why the tmpfile data does not match the template data.
