|
|
.Sh NAME
|
|
.Nm setproctitle
|
|
.Nd set the process title for
|
|
.Xr ps 1
|
|
.Sh SYNOPSIS
|
|
.Fd #include <sys/types.h>
|
|
.Fd #include <unistd.h>
|
|
.Ft void
|
|
.Fn setproctitle "const char *fmt" "..."
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn 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.
|
|
If the
|
|
.Va fmt
|
|
argument begins with a
|
|
.Dq -
|
|
character, the executable's name is skipped.
|
|
.Pp
|
|
If
|
|
.Va fmt
|
|
is NULL, the process title is restored.
|
|
.Sh EXAMPLES
|
|
To set the title on a daemon to indicate its activity:
|
|
.Bd -literal -offset indent
|
|
setproctitle("talking to %s", inet_ntoa(addr));

|

|
|
.Xr ps 1 ,
|
|
.Xr w 1 ,
|
|
.Xr kvm 3 ,
|
|
.Xr kvm_getargv 3 ,
|
|
.Xr printf 3
|
|
.Sh STANDARDS
|
|
.Fn 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
|
|
.Fn setproctitle
|
|
if present.
|
|
.Pp
|
|
Unfortunately, it is possible that there are other calling conventions
|
|
to other versions of
|
|
.Fn 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
|
|
.Nx
|
|
and
|
|
.Tn BSD/OS .
|
|
.Sh HISTORY
|
|
.Fn setproctitle
|
|
first appeared in
|
|
.Fx 2.2 .
|
|
Other operating systems have
|
|
similar functions.
