Function Documentation

char* G__location_path ( void  )

Get current location path.

\returnchar* to location path

Definition at line 72 of file location.c.

References G_gisdbase(), G_location(), render::name, and sprintf().

Referenced by G__file_name(), G__file_name_misc(), and G_location_path().

char* G_location ( void  )

Get current location name.

Returns the name of the current database location. This routine should be used by modules that need to display the current location to the user. See Locations for an explanation of locations.

\returnchar* tolocation name

Definition at line 61 of file location.c.

References G_getenv().

Referenced by G__location_path(), G__make_mapset(), G_get_projinfo(), G_get_projunits(), I_location_info(), Vect__open_old(), Vect_delete(), Vect_hist_command(), and Vect_open_new().

char* G_location_path ( void  )

Get current location directory.

Returns the full UNIX path name of the current database location. For example, if the user is working in location spearfish in the /home/user/grassdata database directory, this routine will return a string which looks like /home/user/grassdata/spearfish.
