Touchingthe secret data is easy to do. You simply add a line of code to the function to read the data in memory, but be wary of the optimizer again. You can fool the optimizer by casting the pointer to a volatile pointer because volatile pointers can be manipulated outside the scope of...
While reviewing the file, I noticed a few areas that could be improved: The "Main loop" comment on line 66 could be more descriptive or removed if unnecessary. There's an unused static counter variablecounteron line 67. Consider removing it if it's not needed. ...
The problem in the given code is the pointers arithmetic, to be more exact, the use of non-memsize types for this arithmetic:end += domainWidth * domainHeght * domainDepth;The error is that with the 64-bit platform the pointer end will never have the increment larger than 4 gigabytes....
For reference, another language that has null pointers, Java, raises an exception on Optional.of(null).In general, I expect the explicitly requested creation of a Some to fail if no actual value to wrap in it is supplied.If one explicitly wants to let Maybe decide whether to create a ...
