It seems that they missed when they wrote comments. And this is repeated everywhere, and not just in the implementation for any particular platform. And the question arises - to trust the documentation or the names of the variables?
Thanks for pointing that out!
It seems to be a wrapper documentation issue as the source file is correct: https://gitlab.linphone.org/BC/public/liblinphone/-/blob/master/include/linphone/types.h#L749
I'll see what I can do to fix it.
