For int, it returns -1, if it sees the INT flag. I think of the following behavior: if it sees the INT flag and pv is NULL, return -1; else, return 1; ________________________________ From: Daniel-Constantin Mierla &lt;miconda(a)gmail.com&gt; Sent: Friday, August 4, 2023 3:37:27 PM To: Kamailio (SER) - Development Mailing List Subject: [sr-dev] Re: Question for not_empty() config function Hello, I guess it was designed for string. What does it return now for int type? Overall, for me it would be fine to extend for int, or maybe better add a new function if someone considers this one becomes confusing.

Can I extend it to work with INTs too? e.g. if pv not NULL and INT flag, return 1. This would help, because one won't need to know the type of the pvar beforehand, for using this function. Or is it meant to be used only with string pv only?
