Re^3: XS: returning a 64-bit unsigned int?

sv_setuv_mg(sv, uv); is actually what you want unless you follow the sv_setuv(sv, uv); with SvSETMAGIC(sv);.

Are you sure? (And can you explain why magic is needed?) Because it seems to work just fine without any magic? Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice.	[reply]

If there's no set magic attached, SvSETMAGIC(sv) does nothing. If there is, SvSETMAGIC(sv) makes it work. Knowing you and having just seen how you plan to use this, I know you'll simply assume there's no magic attached to the scalar.	[reply]
