[Cogito]

Peff, for the people asking in the thread, is there a place where correct alternatives are suggested or demonstrated?

I know there are a few different places that talk about how to use git's internal machinery, but not sure if any are specific to these banned functions.

The original commits mentions git's strbuf API[0] and its xsnprintf, a variant of snprintf which asserts that the destination buffer was big enough[1] (rather than just return truncation information).

For other codebases, snprintf is the usual recommendation, and careful straight buffer manipulation (mem*) iff performances are a concern.

The commit messages that add them to banned.h discuss alternatives, though most of the explanations are Git-specific and assume you'll look elsewhere to figure out how to actually use those alternatives.
