Hello, Is it possible with NativeBoost to create a binding for a variadic function ? I've seen the printf example in NBCPrinter but this implementation is kind of cheating since it always pass just a %s as format and one already formatted string to the C function. I've written a simple variadic function which adds every integer it receives as argument (first argument is for the number of following arguments) : int add(int number,...); In Pharo I've tried something like this : *add: *number *arg1: *first *arg2: *second
<primitive: #primitiveNativeCall module: #NativeBoostPlugin>
^ self nbCall: #( int add (int number, int first, int second)) module: 'libMyLib.so'
and it works fine with two arguments. Basically, doing so, I would need one method per number of arguments so it's not very cool. I thought that maybe I could pass an array as argument to my Pharo method but I didn't really find a way to figure out how to define the nbCall without having a "Generic failure". *add: *number *args: *anArray
<primitive: #primitiveNativeCall module: #NativeBoostPlugin>
^ self nbCall: #( int add (int number, ??? anArray)) module: 'libMyLib.so'
Do you have an idea ? Thanks, Matthieu
