Antoine Pitrou commented on ARROW-555:
--------------------------------------

I'm assuming C functions btw, but those may just as well be C++ functions (with 
the C wrappers on the Gandiva side). However, they can't use certain C++ stdlib 
facilities such as {{iostream}} (hence the split between {{Decimal}} and 
{{BasicDecimal}}).
