The vask library is just a simplified wrapper for curses.  The GISDBASE,
LOCATION and MAPSET are written to the ~/.grassrc5 file.  If you're
interested in the session start-up code, have a look in
src/general/init/, which among other things sets the environment
variables above.  Also good to poke around src/libes/gis/ to see how
many things are handled regarding database management, I/O, etc... Don't
rely on the Programming manual.  It's helpful, but doesn't document a
lot of stuff (some things just aren't documented).

It gets them from the environment...
