_putenv_s and _wputenv_s may change the value of _environ and _wenviron, and thereby invalidate the envp argument to main and the _wenvp argument to wmain. Therefore, it is safer to use _environ or _wenviron to access the environment information. For more information about the ...

However, the modified environment can be passed to any new processes that are created by _spawn, _exec, or system, and these new processes get any new items that are added by _putenv_s and _wputenv_s.Don't change an environment entry directly; instead, use _putenv_s or _wputenv_s ...

_putenv_s and _wputenv_s affect only the environment that is local to the current process; you cannot use them to modify the command-level environment. That is, these functions operate only on data structures accessible to the run-time library and not on the environment "segment" created fo...
