Comment (by eighthave):

 The workings of both logcat and syslog are not really officially
 documented anywhere, or at least I've never found it.  So it seems source
 code is the way.  Android's libc is called Bionic, so that's where the
 syslog calls come from: https://android.googlesource.com/platform/bionic

 And typical Android, liblog and lgocat source code is somewhere else
 entirely:
 https://android.googlesource.com/platform/system/core

 As far as I know, there is never a `syslogd` running on Android, so I
 don't understand out the strings get from `syslog()` to logcat.  I imagine
 it is via `/dev/log/*` device or something similar.
