EdmiError edmiAggrValueCompare(SdaiAggr operand1,
SdaiAggr operand2,
SdaiLogical *result);
Implements the Express Aggregate Value Compare> operation as defined in section 12.2.1.6 Aggregate value comparisons; in ISO 10303-11:1994(E) : The EXPRESS Language Reference Manual. This operation is only applicable to aggregates in data models. The actual data models must be open before this function can be successfully performed.
Arguments
| Type | Name | Comment |
| SdaiAggr | operand1 | A numeric aggregateID that uniquely identifies the aggregate instance used as operand1 (left operand) in the operation The aggregateID is returned when the aggregate is created or it can be retrieved by an EDMinterface get operation. |
| SdaiAggr | operand2 | A numeric aggregateID that uniquely identifies the aggregate instance used as operand2 (right operand) in the operation. The aggregateID is returned when the aggregate is created or it can be retrieved by an EDMinterface get operation. |
| SdaiLogical | result | Address of a variable that will receive the result of the aggregate value compare operation. |
