The same principles can be applied to any language and any operating

The main point is that the GRASS libraries expect certain environment
variables to be set (mainly GISBASE and GISRC), and the file
referenced by GISRC should contain settings for GISDBASE,

There is a list of environment variables in the file
$GIBASE/docs/html/variables.html (lib/init/variables.html in the
source tree).

Variables relating to specific display drivers are listed in the
driver's documentation (e.g. pngdriver.html for the PNG driver).

You can use g.mapset or g.gisenv to change these parameters.
