The mi_lo_specget_flags() function obtains from an LO-specification structure the attributes flag for a smart large object.

mi_integer mi_lo_specget_flags(LO_spec)

MI_LO_SPEC *LO_spec;

LO_spec

is a pointer to the LO-specification structure from which to obtain the flag value.

The mi_lo_specget_flags() function is the LO-specification accessor function that returns the attributes flag from a set of storage characteristics. The attributes flag provides the following information about a smart large object:

• Whether to use logging on the smart large object
• Whether to store the time of last access for the smart large object

Constants for these attributes are masked together into the single attributes-flag value. Therefore, to obtain a particular attribute, you must use the bitwise AND operator (&) to mask the attributes flag, as the following code fragment shows:

create_flags = mi_lo_specget_flags(LO_spec)
if ( create_flags & MI_LO_ATTR_LOG )
	/* logging is on */


Important: Before you call mi_lo_specget_flags(), you must put storage characteristics into an LO-specification structure. 

You can use any of the following functions to initialize the LO-specification structure:

• The mi_lo_colinfo_by_ids() or mi_lo_colinfo_by_name() function put storage characteristics that are associated with a particular CLOB or BLOB column in an LO-specification structure.
• The mi_lo_stat_cspec() function puts storage characteristics of an existing smart large object in an LO-specification.
• The mi_lo_specset_flags() function sets the attributes flag in an LO-specification structure.

The mi_lo_specget_flags() function obtains the current value for the attributes flag from the LO-specification structure that LO_spec references.

See the descriptions of the following functions: mi_lo_colinfo_by_ids(), mi_lo_colinfo_by_name(), mi_lo_spec_free(), mi_lo_spec_init(), mi_lo_specset_flags(), and mi_lo_stat_cspec().

For more information on the attributes flag of a smart large object, see Storage Characteristics. For information on how to use the mi_lo_specget_flags() function, see The LO-Specification Structure, and Defining User-Specified Storage Characteristics.
