Get Last Error

Usage

status = flex_get_last_error(u8 boardID, u16* commandID, u16* resourceID, i32* errorCode);

Purpose

Gets detailed information about the last error generated by a high-level NI-Motion function in the course of executing other NI-Motion functions.

Parameters

Name	Type	Description
boardID	u8	assigned by Measurement & Automation Explorer (MAX)
commandID	u16*	command ID number
resourceID	u16*	resource ID number
errorCode	i32*	error code

Parameter Discussion

errorCode is the error code value, as defined in the file motnErr.h in the NI-Motion include directory.

commandID is the command ID of the function that generated the error.

resourceID is the resource (e.g. axis, vector space, ADC, etc.) that generated the error.

Using This Function

If the Initialize function returns an error, you can call this function to determine the specific NI-Motion function and resource that generated the error. You can then call the Get Error Description function, which formats a string for you with the function name, resource ID and error description.
