Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The mi_issmall_data() macro finds out whether the data in this multirepresentational opaque type is in a smart large object.

mi_boolean mi_issmall_data(size)

mi_integer size;

size	is an MI_MULTIREP_SIZE. It is typically a field in the internal representation of a multirepresentational data type.

Valid in Client LIBMI Application?	Valid in User-Defined Routine?
Yes	Yes

The mi_issmall_data() macro determines if size, the value of the threshold-tracking field in a multirepresentational opaque type, is equal to the MI_MULTIREP_LARGE constant. If the multirepresentational data is stored in a smart large object, the threshold-tracking field should contain the MI_MULTIREP_LARGE constant. Otherwise, the data is stored in-row and this field should contain the MI_MULTIREP_SMALL constant.

The mi_issmall_data() macro is useful in the assign(), destroy(), or output function of a multirepresentational data type to determine whether the associated data is stored in a smart large object or in-row.

See the description of the mi_set_large() function.
