C

Hey!

Is there a shortcut for this "pattern":
c = (a -b);
if (c != 0) return c;
c = (d-c);
if (c != 0); return c;
//...


I don't quite see how I can avoid storing c, because it matters if it's <0 or >0... or does it get optimized away anyway?

qsort, bsearch, and so on take a function whose arguments need to be "const void *p". Is there a way to cast them into the right type right in the function definition, without needing to either introduce two new variables, or cast them every time they're used?

Thanks /prog/!

Your `pattern' is complete nonsense, but

c = (a -b);
if (c != 0) return c;

can be replaced with

if (c = (a -b)) return c;

if you [i]really[i] need to use your bullshit `pattern'.

So I can just make a macro for that expression, and should be done with it.
Now you have two problems.
