[GRASS-user] Setting GRASS environment variable in a C program - step two

[rabotin]

Thanks for helping me,
as you wrote I change

>   
to:


> 	std::cout << driver << std::endl;
And I got a zero value return . So my driver isn't set ?
Is the problem from the following lines :
setenv("DBF_DRIVER","dbf",1);
setenv("DB_DATABASE","$GISDBASE/$LOCATION_NAME/$MAPSET/dbf",1);

I didn't write but I use grass 6.4 on ubuntu 9.10.
Do you know other commands to test or to set the dbf driver than 
db_start_driver command ?

Cheers

Mick
