.Dt SETPROCTITLE 3
.Os
.Sh NAME
.Nm setproctitle
.Nd set process title
.Sh SYNOPSIS
.In setproctitle.h
.Ft int
.Fn setproctitle "const char *fmt" "..."
.Sh DESCRIPTION
The
.Fn setproctitle
function sets the invoking process's title.
The process title is set to the last component of the program
name, followed by a colon, a single space, and the formatted string specified
by
.Fa fmt .
If
.Fa fmt
is
.Dv NULL ,
the colon and formatted string are omitted.
.Sh EXAMPLES
Set the process title to the program name, with no further information:
.Bd -literal -offset indent
setproctitle(0);
.Ed
.Pp
Set the process title to the program name, an informational string,
and the process ID:
.Bd -literal -offset indent
setproctitle("foo! (%d)", getpid());
.Ed
.Sh SEE ALSO
.Xr ps 1 ,
.Xr w 1 ,
.Xr printf 3
.Sh HISTORY
The
.Fn setproctitle
function first appeared in
.Nx 0.9a .
The
.Fn setproctitle
library first appeared in
.Os ALT GNU/Linux .
.Sh AUTHORS
The
.Nm
library was written for the ALT GNU/Linux by
Dmitry V. Levin.
.br
This manual page was written for the NetBSD Project by
Christopher G. Demetriou.
.Sh CAVEATS
It is important never to pass a string with user-supplied data as a
format without using
.Ql %s .
An attacker can put format specifiers in the string to mangle the stack,
leading to a possible security hole.
This holds true even if the string has been built
.Dq by hand
using a function like
.Fn snprintf ,
as the resulting string may still contain user-supplied conversion specifiers
for later interpolation by
.Fn setproctitle .
.Pp
Always be sure to use the proper secure idiom:
.Bd -literal -offset indent
setproctitle("%s", string);
.Ed
.Pp
The
.Fn setproctitle
function clobbers the argv (array of argument strings passed to the
process).  If this data is going to be used after first
.Fn setproctitle
invocation, it should be saved in another memory location.
