Thanks for helping me,
as you wrote I change
std::cout << &driver << std::endl;
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

After that , using db_open_database(driver,&handle) command launch a

Possibly; change:
std::cout << &driver << std::endl;
to:
std::cout << driver << std::endl;
to confirm this.
Are some commands missing to access or start dbf driver in my script ?
I can't see anything wrong, other than failing to check the return
value from db_start_driver().
