mi_large_object_increfcount()

The mi_large_object_increfcount() function increments the reference count of a smart large object.

Syntax

#include "miloback.h"

...
mi_integer mi_large_object_increfcount(conn, LO_handle)

		MI_CONNECTION *conn;

		MI_LOHANDLE *LO_handle; 


conn
is a pointer to the connection descriptor that a previous call to mi_open() or mi_server_connect() has established.

LO_handle
is the handle for the smart large object. An MI_LOHANDLE value is returned by any routine that creates a smart large object or in query results that mi_value() returns.

Usage

The assign() function can call the mi_large_object_increfcount() function. This function must be called from a assign() support function of any opaque data type that contains smart large objects.

Tip: Informix provides the mi_large_object_increfcount() function for backward compatibility only. Use the mi_lo_increfcount() function for all new DataBlade routines.

Return Values

On success, returns the new reference count; on failure, returns MI_ERROR.
