#include <lcio.h> unsigned long ktell(FILE *f);
ktell function returns the RBA of the current record of the stream
associated with the FILE object addressed by f. If there is no
current record when ktell is called, an error indication is returned.
For an ESDS, a record's RBA is stored in its key field, so in general,
using ktell is not necessary with an ESDS.
ktell function returns the RBA of the current record if it is successful,
or -1UL if an error occurs.
