Client APIs and toolsYou can use the HCL OneDB™ implementation of client APIs to develop applications for HCL OneDB™ database servers.
HCL OneDB™ ODBC Driver GuideThe HCL OneDB™ ODBC Driver Programmer's Manual serves as a user guide and reference for HCL OneDB™ ODBC Driver, which is the HCL OneDB™ implementation of the Microsoft™ Open Database Connectivity (ODBC) interface, Version 3.0.
Client functionsThese topics describe the HCL OneDB™ ODBC Driver client functions. Use these functions to access and manipulate smart large objects and rows and collections.
Functions for smart large objectsThis section describes each client function that the driver provides for smart large objects.
The ifx_lo_tell() functionThe ifx_lo_tell() function retrieves the current file or seek position for an open smart large object.

The ifx_lo_tell() function

The ifx_lo_tell() function retrieves the current file or seek position for an open smart large object.

Syntax

ifx_lo_tell(lofd, seek_pos)

The function accepts the following arguments.


Argument	Type	Use	Description
lofd	SQL_INTEGER	Input	Smart-large-object file descriptor
seek_pos	SQL_BIGINT	I/O	New seek position, which is the offset for the next read or write operation on the smart large object. Instead of using the default HCL OneDB™ ODBC Driver C data type of SQL_C_CHAR for seek_pos, use SQL_C_LONG.

The ifx_lo_tell() function retrieves the current file or seek position for an open smart large object.

This function works correctly for smart large objects up to 2 gigabytes in size.
