Properties for Status Simulation in IviDmm

When an IviDmm driver VI is called, the driver queries whether NISDMM_ATTR_SIMULATE_STATUS_CODE is enabled. If enabled, the driver gets the appropriate VI's simulation status code. If the value of the simulation status code represents a warning (has a positive value), then it is returned as the VI's return status only if no other error or warning occurred before the VI ends. If the value of the simulation status code represents an error (has a negative value), then it is returned as the VI's return status only if no other error occurred before the VI ends.

The following IviDmm VIs do not support status code simulation:

• IviDmm Get Error
• IviDmm Clear Error
• IviDmm Get Next Interchange Warning
• IviDmm Reset Next Interchange Warning
• IviDmm Clear Next Interchange Warning
• IviDmm Get Next Coercion Record

Each VI supported by the IviDmm class driver has a corresponding property that determines the status code to return when status code simulation is enabled. The following table lists the status code properties and the VI for which they return a value. These properties are all of type ViInt32, non-readable, and non-channel based.

Note  In the following table, the literal string NISDMM_ATTR_ precedes all property names.
