+.Sh DESCRIPTION
+The

+function
+is the converse of

+it returns a pointer to the parent directory of the pathname pointed to by

+.Sh WARNINGS
+.Fn dirname
+returns a pointer to internal static storage space that will be overwritten

+.Pp
+Other vendor implementations of

+.Dt SETPROCTITLE 3
+.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));
+.Ed
+.Sh SEE ALSO
+.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.
+.Sh AUTHORS
+.An Peter Wemm Aq peter@FreeBSD.org
