This was an interesting lesson for me. Not only did pretty much every commenter miss this point, but I did too! We were all talking about better ways to use memcmp(), such as whether to use the "!= 0" or not, or my memeq() wrapper. Those are all good things to consider if memcmp() is the right solution in the first place. I only had the "aha" moment after I took a break for a long walk and dinner. I should do that more often before assuming I have the right answer... :-) Maybe this is an example of what they call an XY Problem: https://en.wikipedia.org/wiki/XY_problem https://en.wikipedia.org/wiki/XY_problem
