NetBSD support in htop(1)
|
|
===
|
|
|
|
This implementation utilizes kvm_getprocs(3), sysctl(3), etc, eliminating the
|
|
need for mount_procfs(8) with Linux compatibility enabled.
|
|
|
|
The implementation was initially based on the OpenBSD support in htop(1).

Notes on NetBSD curses
|
|
---
|
|
|
|
NetBSD is one of the last operating systems to use and maintain its own
|
|
implementation of Curses.
|
|
|
|
htop(1) can be compiled against either ncurses or NetBSD's curses(3).
|
|
In order for NetBSD's libcurses to be used, htop(1) must be configured with
|
|
`--disable-unicode`. This is necessary because htop(1) with Unicode enabled
|
|
directly accesses ncurses's cchar_t struct, which has different contents
|
|
in NetBSD's curses.
|
|
|
|
Versions of libcurses in NetBSD 9 and prior have no mouse support
|
|
(this is an ncurses extension). Newer versions contain no-op mouse functions
|
|
for compatibility with ncurses.
|
|
|
|
What needs improvement
|
|
---
|
|
|
|
* Kernel and userspace threads are not displayed or counted -
|
|
maybe look at NetBSD top(1).
|
|
* Battery display - use envsys(4).
|
|
* Support for compiling using libcurses's Unicode support.
|
|
* Support for fstat(1) (view open files, like lsof(8) on Linux).
|
|
* Support for ktrace(1) (like strace(1) on Linux).
