| <i>Getenv</i> fetches the environment value associated with <i>name</i> into |
| memory allocated with <a href="../man3/malloc.html"><i>malloc</i>(3)</a>, 0-terminates it, and returns |
| a pointer to that area. If no file exists, 0 is returned. |

| |
| <i>Putenv</i> sets the environment value associated with <i>name</i> to <i>val</i>.<br> |
