✅ Exception Handling for NRE without modifying every call.
I have a ReadData function which reads the memory of a process. If the process exits or crashes during the read, an exception is thrown and control is handed to the catch block. However, the calling function (the function that calls ReadData) can sometimes throw an NRE if the ReadData was aborted and returned null instead of a byte[]. How can I avoid the NREs without needing to change every single call of ReadData? Ideally I would abort the calling function as if it had never been called but I know that would require a large scale rewrite. I have toyed with the idea of modifying the ReadData signature to return a tuple of type (byte[], bool) and changing the behaviour of the calling function depending on the success of the ReadData (bool) but this would also require custom behaviour for every call. There are about 20 calls and I figure adding custom behaviour or exception handling for all of them is inefficient and bad practice. Any solutions?
