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

In addition to the already mentioned 'goto examples', the do ... while (0) idiom is sometimes used in a macro definition to provide for brackets in the definition and still have the compiler work with adding a semi colon to the end of a macro call.
