-LOCAL FUNCTION
-
-	save_inferior_pid - Save inferior_pid on the cleanup list
-	restore_inferior_pid - Restore inferior_pid from the cleanup list
-
-SYNOPSIS
-
-	struct cleanup *save_inferior_pid ()
-	void restore_inferior_pid (int pid)
-
-DESCRIPTION
-
-	These two functions act in unison to restore inferior_pid in
-	case of an error.
-
-NOTES
-
-	inferior_pid is a global variable that needs to be changed by many of
-	these routines before calling functions in procfs.c.  In order to
-	guarantee that inferior_pid gets restored (in case of errors), you
-	need to call save_inferior_pid before changing it.  At the end of the
-	function, you should invoke do_cleanups to restore it.
