/* gethostn - a small diagnostic utility to show what the
|
2 |
* gethostname() API returns. Of course, this tool duplicates
|
|
3 |
* functionality already found in other tools. But the point is
|
|
4 |
* that the API shall be called by a program that is compiled like
|
|
5 |
* rsyslogd and does exactly what rsyslog does.
