The identifier printf() can also be a macro... On 9/23/16 1:15 , Esteban Lorenzano wrote:

along with what Andres says, also no, you do not have support for variadic functions. what you do this is to declare your functions as if they were non-variadic:

pritnf: format intValue: number self ffiCall: #(int printf(String format, int number))

that will work… yes is not the best in the word, but it works :)

I wouldn't do that if I were you. The manual says fcntl() can be a macro, and you can't call a macro from an FFI.

Hi guys,

I am wondering if I can wrap some variadic functions (with optional arguments) with UFFI. Is this possible? If true, how so? For my particular use case, I am checking if I can call fcntl() which has a third optional argument.

Thanks in advance,
