Subject: [binutils-gdb] Make TUI window handle a unique_ptr
Date: Wed, 16 Oct 2019 14:35:00 -0000 [thread overview]

Make TUI window handle a unique_ptr
This changes tui_gen_win_info::handle to be a specialization of
unique_ptr. This is perhaps mildly uglier in some spots, due to the
proliferation of "get"; but on the other hand it cleans up some manual
management and it allows for the removal of tui_delete_win.
