moused is a mouse daemon on FreeBSD systems that works with the console driver to support mouse operations in the text console and user programs.
[1] It first appeared in FreeBSD 2.2 and is currently located in /usr/sbin/moused.
A user process that wants to use the mouse simply opens /dev/sysmouse and reads from it like a normal file.
This makes it possible for the console and user processes such as the X Window System to share the mouse.
