• int * present — output variable indicating whether data was provided or not.

💅 DESCRIPTION 💅

okay so this function gets the PSKC KeyPackage Key AlgorithmParameters ResponseFormat CheckDigits value. it’s giving extremely specific and honestly iconic for it ✨

This attribute indicates whether the device needs to append a Luhn check digit, as defined in [ISOIEC7812], to the response. This is only valid if the 'Encoding' attribute is set to 'DECIMAL' — like, that’s the vibe check, no cap.

If the value is TRUE, then the device will append a Luhn check digit to the response. If the value is FALSE, then the device will not append a Luhn check digit to the response. simple as that 💖

If present is non-NULL, it will be 0 if the field is not present or 1 if it was present. yes bestie, it’s literally telling you whether the field showed up or not 🦋

🔥 RETURNS 🔥

1 to indicate a CheckDigits value of true, or 0 to indicate false. periodt 💅
