Ivi_InvalidateAllAttributes
Usage
ViStatus Ivi_InvalidateAllAttributes(ViSession vi);
Purpose
This function invalidates the cache values of all instances of all attributes for the session.
Invalidating a cache value for an attribute ensures that the next call to an Ivi_GetAttribute or Ivi_SetAttribute function on the attribute invokes the read or write callback for the attribute.
Parameters
| Name | Type | Description |
|---|---|---|
| vi | ViSession |
The ViSession handle that you obtain from Ivi_SpecificDriverNew. The handle identifies a particular IVI session. |
Return Value
Contains the status code that the function call returns. IVI engine functions can return error and warning values from several sets of status codes. Some status codes are unique to the IVI engine. Other status codes are the same codes that VISA Library functions return. Still others are error or warning values that functions in specific instrument drivers return. Each set of status codes has its own numeric range.
Regardless of the source of the status code, 0 always indicates success, a positive value indicates a warning, and a negative value indicates an error.
