Implement basic percentage calculation for wifi_perc. With this
commit, the function returns correct percentage, since the max
of what /proc/net/wireless returns is 70.
The HDR variable is used for general purpose headers, which are not
given in this project. arg.h and config.h are only needed for
slstatus.c, not every component $(COM:=.c).
This also fixes a problem introduced in
e04a385364, where config.h is pulled into
the tarball.
For multiple reasons the program is now split:
- Make future porting to OpenBSD easier
- Assign header includes to individiual functions
- Make future program extensions easier
- Recompile only changed parts
This commit introduces the cpu_iowait item, this is the percentage
of cpu time spent waiting on disks. High numbers typically indicate
that your system is not responsive due to disk IO.
This commit also avoid sleeping inside the cpu_perc and cpu_iowait
functions: waiting in either one implies lost info for the other.

We remove the hack with the sleep and global "delay"-variable and use a
monotonic clock to derive the desired monotonic properties of the tool.
Inside each function that demands a personal delay we can then just do a
nanosleep() and be done with it.
It's a shame that timespec is so ugly to work with, but there's really
no way to make it more beautiful. However, at this cost though we
finally can set the interval times in milliseconds and not only just
seconds.
We remove setlocale(), because nothing good ever came out of this
function.
Besides that we have some more code refactoring, especially in the
argument loop which saves us a bit of complexity.
- Added a check for the return value of XOpenDisplay() in main().
This fixes a possible NULL-deref.
- Removed unnsecessary XOpenDisplay and XCloseDisplay from
keyboard_indicators(). The ones in main() are sufficent.
d-flag: There's no need for that, use the &-operator or fork+exec in a
non-shell-context. In the latter case you get the PID for free.
v-flag: If you want to find out which version of a package is installed,
consult your package manager. That's his job.
