They are exclusive of one another, and they both provide the process
label via /proc/pid/attr/current.  libselinux wraps that kernel
interface with getcon() (for current context) and getpidcon() (for
context of a given pid), which internally handle the allocation of the
buffer and will deal with label translation if using mcstransd.

So if you want the code to work with either, you'd directly
read /proc/pid/attr/current and display the resulting string.  If you
want to be SELinux-specific and include functionality like MLS label
translation, you'd use getpidcon(3).
