All,

mod_jk for httpd requires APR, which includes its own version of snprintf, apr_snprintf.

mod_jk for IIS won't usually include APR as a dependency, so we have to rely on the local Windows environment's implementation of snprintf which, for very old Windows versions isn't guaranteed.

Have we moved past that, now? Can we rely on Windows always providing snprintf at this point?

The earliest versions of Windows we need to support are:
- Windows 11
- Windows Server 2016

AI tells me that Visual Studio 2015 is the first version that guarantees support for snprintf. But it really comes down to the msvcrt.dll used both to build and also on the target system. Right?

I seem to recall struggling to build various native components when we are at the mercy of msvcrt.dll. Mark, do you build mod_jk statically for ISS? Actually, that doesn't make any sense, does it... how much of a pain is this in Windows-land?
