To detect if pcscd is running yo can check if /var/run/pcscd/pcscd.pid
exists and contain the pid of a running pcscd process.
But the file name may be in a different place and it not documented.
You should NOT use that.

I don't understand why you would want to know if pcscd if running.
This is not the business of the application. Just use the WinSCard
(PC/SC) API.

It looks like a bug in the pcsc-lite RedHat/Centos package. The pcscd
sockey is not activated.
I added my comments in https://bugzilla.redhat.com/show_bug.cgi?id=1545027
