My apologies if my tone was not friendly, this was not my intention.

Hey, there is absolutely no reason why you should apologize... your tone is very friendly...and thank you again for your answer.

Given the current interface I find your requests quite reasonable. I'm sure that if you provide a patch for the functions you are suggesting, with documentation and test, the author/maintainer will accept them.

My hope was that the maintainer himself will do it. Writing the code for the find functions and other "easy" ones (like setting a range of bits to true, setting trailing zeros to true, etc) will probably take a few minutes. For me, it will at least take several days, as I first would have to study the source code of the class (although it is not all too long). btw, who is the maintainer of dynamic_bitset? best, David ___________________________________________________________ SMS schreiben mit WEB.DE FreeMail - einfach, schnell und kostenguenstig.
