CTHANDLE hSession = ctdbAllocSession(CTSESSION_CTREE);

CTHANDLE hTable = ctdbAllocTable(hSession);

CTHANDLE hRecord = ctdbAllocRecord(hTable);

NINT datno, count = 0;

/* logon to c-tree */

ctdbLogon(hSession, SERVER, USER, PASSWD);

/* open the file using c-tree ISAM */

datno = (NINT)OPNRFILX((COUNT) -1, "test309.dat", (COUNT)0, NULL);)

/* attach to table */

ctdbAttachTable(hTable, datno);

{

count++;

}
