There's other code checking tools (e.g. splint) that say to never use sprintf and to always use snprintf instead; the manpage on my computer for sprintf also says to always use snprintf instead. For this reason some projects do #pragma GCC poison sprintf in a header file, so sprintf can't actually be used instead in those cases.
