Module Name: src
Committed By: roy
Date: Mon Mar 23 13:37:37 UTC 2020
Modified Files:
src/distrib/sets/lists/comp: mi
src/lib/libcurses: Makefile curses.h
Added Files:
src/lib/libcurses: mouse.c
Log Message:
curses: Add stubs for mouse functions
No mouse support actually included.
But that doesn't matter because most terms don't actually support a mouse.
We should look into hooking these into wsmouse(4) and xterm mouse
in the future.
Compatable with nCurses mouse API version 2.
