The ifx_lo_t structure
The LO-pointer structure, ifx_lo_t, serves as a reference to a smart large object. It provides security-related information and holds information about the actual disk location of the smart large object.
The locator.h header file defines the LO-pointer
structure so you must include the locator.h file
in your programs
that access this structure.
Important: The LO-pointer structure, ifx_lo_t,
is an opaque structure to programs.
That is, you do not access its internal structure directly. The internal
structure of ifx_lo_t might change. Therefore, to create portable
code, use the correct library
function to use this structure.
The LO-pointer structure, not the CLOB or BLOB data itself, is stored in a CLOB or BLOB column in the database. Therefore, SQL statements such as INSERT and SELECT accept an LO-pointer structure as the column value for a smart-large-object column. You declare the host variable to hold the value of a smart large object as an ifx_lo_t structure.
