Good point about `putenv()`; however there is also `setenv()`, which does make a copy, so you are wrong about `getenv()` in general. POSIX explicitly states "The string [returned by getenv] may be overwritten by a subsequent call to getenv(), setenv(), unsetenv(), or putenv()" (https://pubs.opengroup.org/onlinepubs/9699919799.2008edition...). |
