I used the TPB given in the doc.

static char isc_tpb[] = {isc_tpb_version3,
isc_tpb_write,
isc_tpb_concurrency,
isc_tpb_nowait,
isc_tpb_protected, isc_tpb_lock_read, "COUNTRY",
isc_tpb_protected, isc_tpb_lock_write, "EMPLOYEE"};

This does not compile since it cannot convert char* to char.

Any idea what the correct TPB format is ?

Thanks!
