- Subject: [PATCH 34/66] Change tui_update_source_window for better type safety
- References: <20190623224329.16060-1-tom@tromey.com>
tui_update_source_window can only be called for source and disassembly
windows, so change the argument type to enforce this at compile time.
2019-06-23 Tom Tromey <tom@tromey.com>
* tui/tui-winsource.h (tui_update_source_window)
(tui_update_source_window_as_is): Change parameter type.
* tui/tui-winsource.c (tui_update_source_window): Change win_info
to be a tui_source_window_base.
(tui_update_source_window_as_is): Likewise.
* tui/tui-win.c (make_visible_with_new_height): Update.
