While most Unix-like systems use 16-bit user IDs, Linux supports 32-bit UIDs since version 2.6. UIDs above 65535 are used for UID namespacing of containers, where a container has its own set of 16-bit user IDs. Processes in such containers will have (much) larger UIDs than 65535. Because the current format strings for `ST_UID` and `USER` are `%5d` and `%9d` respectively, processes with such UIDs lead to misaligned columns. Dynamically scale the `ST_UID` column and increase the size of `USER` to 10 characters (length of UINT32_MAX) to ensure that the user ID always fits. Additionally: clean up how the titlebuffer size calculation and ensure the PID column has a minimum size of 5. |

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).
- 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).
