What’s the Point of the C Preprocessor, Actually?
- magmaman 5y agoIt's been 2 decades since I last programmed in C. But all I remember of Macros is that some of the most difficult bugs to spot in C code lives in Macros. A missing paranthesis, unthoughtful coding can make it extremely difficult to spot the bug. Also makes code unreadable...Check out Linux source...
- phendrenad2 5y agoI have a rule that macros are always generated by a perl script. The macro syntax is too easy to mess up. Also generating it in a higher-level language makes it easier to comprehend.
- magmaman 5y agoPerl? Well you need a time machine just to reach the present... :) Anyway, that setup sounds too complex...Perl generated macros further expanded by the preprocessor... A bug in that tool path can be the most hard to detect... Good luck!!!
