+ * linux-low.c (linux_detach, linux_join): Change parameter to
+ process_info pointer instead of pid. Adjust.
+ * lynx-low.c (lynx_detach, lynx_join): Likewise.
+ * nto-low.c (nto_detach): Likewise.
+ * spu-low.c (spu_detach, spu_join): Likewise.
+ * win32-low.c (win32_detach, win32_join): Likewise.
+ * server.c (handle_detach, detach_or_kill_for_exit): Adjust.
+ * target.h (struct target_ops) <detach, join>: Change parameter to
+ process_info pointer instead of pid. Adjust all implementations
+ and callers.
+ (detach_inferior, join_inferior): Rename 'pid' parameter to
+ 'proc'.
