The swapctl(2) function fills the swapent struct with 512KB blocks.
As we want to display in GB, i just modified the calculation for this to
get the expected output.
To reproduce the issue:
$ slstatus -s | tee
then it would print only when the stdout buffer is full, by block
of multiple lines.
fflush() makes sure the line is printed at every loop iteration
- Use block for single statement ifs
- Keep lines to reasonable length (current debate as to reasonable)
- When functions return -1 for error test against 0 not -1
- Do not indent cases another level
- Do not test against NULL and 0 explicitly
- Use tabs for indentation, use spaces for alignment
The third value from load_avg (idle) gives us almost the same
information as cpu_iowait. Plus OpenBSD does not offer an iowait value
as Linux and thus the corresponding function would not be portable.
Be consistent with brackets and add a comment for OpenBSD to make it
clearer what the actual intent of the uncommented line is.
In the Makefile, add a dependency of slstatus.o from config.mk.
Granted, this style is definitely not common, but for the short
utility-functions of this program it's just the right choice. This
provides great flexibility, such that in the long run, it will be
possible to also share code between the OS-implementations.
This also keeps the state-keeping at a minimum and makes it clearer
which functions are implemented on which OS without having to jiggle
around with too many files in the process.
