I think this is why there are parantheses around current->uid = 0. gcc has the option -Wparentheses, which gives a warning if you write something like this: if (a = b) doSomething;
But there is no warning if you write it like this: if ((a = b)) doSomething;
The convention is that with these unneeded parantheses, you are signalling that you actually want the assignment here. I would assume other static code analysis tools use this convention as well. |
