do {…} while(false)

Question

I was looking at some code by an individual and noticed he seems to have a pattern in his functions:

 function()
{
 

        

Answer 1

This is just a perversion of while to get the sematics of goto tidy-up without using the word goto.

It's bad form because when you use other loops inside the outer while the breaks become ambiguous to the reader. "Is this supposed to goto exit? or is this intended only to break out of the inner loop?"
