niFgen_ClearError

NI-FGEN C Function

niFgen_ClearError

ViStatus niFgen_ClearError (ViSession vi);

Purpose

Clears the error information for the current execution thread and the IVI session you specify. If you pass VI_NULL for the vi parameter, this function clears the error information only for the current execution thread.

This function sets the error code to VI_SUCCESS (0), and sets the error description string to "" (empty string) .

The IVI Engine also maintains this error information separately for each thread. This feature is useful if you do not have a session handle to pass to the niFgen_ClearError or the niFgen_GetError function, which occurs when a call to the niFgen_init or the niFgen_InitWithOptions function fails.

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.

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.
