Volume display on OpenBSD about dwmblocks

[swindlesmccoop]

I did a bit of investigating and realized that I was using signals wrong...anyways, what I figured out is that I needed my script to actually send the signal to the dwmblocks process. The only problem is that all of the blocks to the right of the block where the signal is defined as 1 are truncated. I have attached my blocks.h file for debugging if that's helpful.

There are two user-defined signals for POSIX Standard signals, SIGUSR1 and SIGUSR2

I also use OpenBSD btw.
For volume control, My dwm/config.h has something like this:
{ MODKEY, XK_equal, spawn, SHCMD("sndioctl output.level=+0.05; pkill -SIGUSR1 dwmblocks") },

In dwmblocks:
{"", "sb-volume", 0, 1},

That looks like it would work. Do you know how to bind the actual media keys like on a laptop (in my case the ThinkPad T420) in config.h so that they can run that command instead of whatever arbitrary command its running?

I think this will do:
{ 0, XF86XK_AudioMute, spawn, SHCMD("pkill -SIGUSR1 dwmblocks") },
{ 0, XF86XK_AudioRaiseVolume, spawn, SHCMD("pkill -SIGUSR1 dwmblocks") },
{ 0, XF86XK_AudioLowerVolume, spawn, SHCMD("pkill -SIGUSR1 dwmblocks") },

Thank you! This is quite literally the exact thing I was looking for. In case anyone finds this on Google or something, in order to fix the error: use of undeclared identifier 'XF86XK_AudioRaiseVolume' error, you need to add a line above all of the keybinds with #include <X11/XF86keysym.h>
