LO_spec

is a pointer to the LO-specification structure from which to obtain the default open flags.

Yes	Yes

The mi_lo_specget_def_open_flags( ) function obtains the current value for the default open-mode flag from the LO-specification structure that LO_spec references. This default open-mode flag is the bit mask that indicates which open mode the mi_lo_open( ) function uses when it opens the smart large object but does not specify an open-mode flag. To override the default open-mode flag, you can specify an open mode as an argument to mi_lo_open( ).

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 puts 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_def_open_flags( ) function sets the default open flags in an LO-specification structure.

MI_OK

indicates that the bit-mask value of the default open flags for the smart large object that LO_spec references.

MI_ERROR

indicates that the function was not successful.
