Hello,

I implemented a #each method in a C extension and uses rb\_yield for each  
iteration of the #each method. Apparently, the break functionality to  
interupt the normal #each iterations does not work when using my own  
#each function. Why does Ruby not break out of the loop, I return  
control to ruby after each rb\_yield call? How can I catch in my C  
function that a break has been issued, or how can I fix this so that it  
has the required behaviour?

Greetings,

Geert.
