niFgen_ResetInterchangeCheck
ViStatus niFgen_ResetInterchangeCheck (ViSession vi);
Purpose
When developing a complex test system that consists of multiple test modules, it is generally a good idea to design the test modules so that they can run in any order. To do so requires ensuring that each test module completely configures the state of each instrument it uses. If a particular test module does not completely configure the state of an instrument, the state of the instrument depends on the configuration from a previously executed test module. If you execute the test modules in a different order, the behavior of the instrument and therefore the entire test module is likely to change. This change in behavior is generally instrument specific and represents an interchangeability problem.
You can use this function to test for such cases. After you call this function, the interchangeability checking algorithms in the specific driver ignore all previous configuration operations. By calling this function at the beginning of a test module, you can determine whether the test module has dependencies on the operation of previously executed test modules.
This function does not clear the interchangeability warnings from the list of previously recorded interchangeability warnings. If you want to guarantee that the niFgen_GetNextInterchangeWarning function only returns those interchangeability warnings that are generated after calling this function, you must clear the list of interchangeability warnings. You can clear the interchangeability warnings list by repeatedly calling the niFgen_GetNextInterchangeWarning function until no more interchangeability warnings are returned. If you are not interested in the content of those warnings, you can call the niFgen_ClearInterchangeWarnings function.
Parameters
| Input | ||
| Name | Type | Description |
| vi | ViSession | Identifies your instrument session. vi is obtained from the niFgen_init or the niFgen_InitWithOptions functions and identifies a particular instrument session. |
Return Value
| Name | Type | Description | ||||||||
| Status | ViStatus | Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. You can examine the status code from each call to an NI-FGEN function to determine if an error occurred.
To obtain a text description of the status code, call the niFgen_error_message function. To obtain additional information about the error condition, call the niFgen_GetError function. To clear the error information from NI-FGEN, call the niFgen_ClearError function. The general meaning of the status code is as follows:
