This looks OK.
In the PRPSINFO code you are using hardwired constants in the strncpy
calls. Maybe you can compute them from macros instead to make sure that we
don't end up with problems later if type sizes change?

Maybe the 16 can be PRPSINFO_OFFSET_PR_PID.

Maybe the 80 can be PRPSINFO_SIZE - PRPSINFO_OFFSET_PR_PSARGS.
it looks like you already did something similar with the memcpy call in the
PRSTATUS code so that looks OK.
