Client APIs and toolsYou can use the HCL OneDB™ implementation of client APIs to develop applications for HCL OneDB™ database servers.
ESQL/C GuideThe HCL OneDB™ ESQL/C Programmer's Manual explains how to use , the HCL OneDB™ implementation of Embedded Structured Query Language (SQL) for C (ESQL/C), to create client applications with database-management capabilities.
What is HCL OneDB™ ESQL/C?
Smart large objectsA smart large object is a data type that stores large, non-relational data objects such as images, sound clips, documents, graphics, maps and other large objects, and allows you to perform read, write, and seek operations on those objects.
Data structures for smart large objects
The LO-specification structureBefore you create a new smart large object, you must allocate an LO-specification structure with the ifx_lo_def_create_spec() function.

The LO-specification structure

Before you create a new smart large object, you must allocate an LO-specification structure with the ifx_lo_def_create_spec() function.

The ifx_lo_def_create_spec() function performs the following tasks:

It allocates a new LO-specification structure, whose pointer you provide as an argument.
It initializes all fields of the LO-specification structure: disk-storage information and create-time flags to the appropriate null values.
