putenv() is deprecated due several drawbacks: the passed buffer becomes part of the environment (not copied), thus the caller needs to allocate a permanent buffer first - and has no way to know whether it might become used later. And it has to fill in the new entry in the correct form (<name>+"="+<value>) setenv() instead is damn simple: pass env variable name and value separately, and no need to care what's going on under the hood.
