Ivi_InterchangeCheck
Usage
ViBoolean = Ivi_InterchangeCheck(ViSession vi);
Purpose
This function returns the current value of the IVI_ATTR_INTERCHANGE_CHECK attribute for the session you specify.
Use Ivi_InterchangeCheck in the high-level functions in class instrument drivers. Ivi_InterchangeCheck provides fast, convenient access to the IVI_ATTR_INTERCHANGE_CHECK attribute because it does no error checking and does not lock the session.
 | Note Do not call this function unless you have already locked the session. |
Parameters
| Name | Type | Description |
|---|---|---|
| vi | ViSession |
The ViSession handle that you obtain from Ivi_SpecificDriverNew. The handle identifies a particular IVI session. |
Return Value
Returns the value of the IVI_ATTR_INTERCHANGE_CHECK attribute. This attribute determines whether class drivers perform interchangeability checking. The specification for each instrument class defines the rules for interchangeability checking for that class.
Values:
| VI_TRUE (1) | Interchange checking on |
| VI_FALSE (0) | Interchange checking off |
If you pass an invalid session handle to the function, this parameter returns VI_FALSE.
