C Data Type Definition

typedef int LOB_LOCATOR;
typedef int LOB_RESULT_LOCATOR;

Usage

BLOBs are passed as locators only, and not automatically loaded into memory. BLOB argument and return types must specify AS LOCATOR in the CREATE FUNCTION statement.

Here is an example using BLOB AS LOCATOR in a UDF definition and LOB_LOCATOR and LOB_RESULT_LOCATOR in the C function declaration.

CREATE FUNCTION F1 (
  A BLOB AS LOCATOR)
RETURNS BLOB AS LOCATOR
 ...;

void f1( LOB_LOCATOR        *a,
         LOB_RESULT_LOCATOR *result,
   ... )
{  ... }
