.Sh SYNOPSIS
|
|
#include <libutil.h>

Link with

|
on the

.Xr cc 1
|
|
command line.
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm setproctitle
|
|
library routine sets the process title that appears on the
|
|
.Xr ps 1
|
|
command.
|
|
.Pp
|
|
The title is set from the executable's name, followed by the
|
|
result of a
|
|
.Xr printf 3
|
|
style expansion of the arguments as specified by the
|
|
.Va fmt
|
|
argument.
|
|
.Pp
|
|
If
|
|
.Va fmt
|
|
is NULL, the process title is reset to simply the name of the executable.

|

To set the title on a daemon to indicate it's activity:

|
.Bd -literal -offset indent
|
|
setproctitle("talking to %s", inet_ntoa(addr));
|
|

.\" This next request is for sections 1, 6, 7 & 8 only

|
.Sh STANDARDS
|
|
.Nm setproctitle
|
|
is implicitly non-standard. Other methods of causing the
|
|
.Xr ps 1
|
|
command line to change, including copying over the argv[0] string are
|
|
also implicitly non-portable. It is preferable to use an operating system
|
|
supplied
|
|
.Nm setproctitle
|
|
if present.
|
|
.Pp
|
|
Unfortunately, it is possible that there are other calling conventions
|
|
to other versions of
|
|
.Nm setproctitle ,
|
|
although none have been found by the author as yet. This is believed to be
|
|
the predominant convention.
|
|
.Pp
|
|
It is thought that the implementation is compatible with other systems,
|
|
including
|
|
.Nm NetBSD
|
|
and
|
|
.Nm BSD/OS .
|
|
.Sh HISTORY
|
|
.Nm setproctitle
|
|
first appeared in FreeBSD at version 2.2. Other operating systems have
|
|
similar functions.
