It is indeed not possible to implement a function with C varargs in
FPC.
I was afraid that's the answer :-(
as an ugly workaround, I wrote a c library that vsnprintf msg and args
to a buffer and then calls a pascal function with no varargs.
It works but, as I said, it's ugly and I'd need to provide a .a for
every platform I plan to use.
Is there a better/simpler way (apart from asking the library
developers
to use a callback with no varargs)?
No.
Not necessarily better than platform specific .a files mentioned by
Luca, but the required playing with stack and registers should be still
doable with a function written in assembler (inside the Pascal sources),
shouldn't it?
