30 cilxs_checkattributevistring Purpose ViStatus cilxs_checkattributevistring (ViSession instrumenthandle, ViChar _VI_FAR channelname[], ViAttr attributeid, ViChar _VI_FAR attributevalue[]); This function checks the validity of a value you specify for a ViString attribute. Parameter List instrumenthandle ViSession The ViSession handle that you obtain from the cilxs_init or cilxs_initwithoptions function. The handle identifies a particular instrument session. Default Value: None channelname ViChar[] If the attribute is channel-based, this parameter specifies the name of the channel on which to check the attribute value. If the attribute is not channel-based, then you set this control to empty string or VI_NULL. Pass the virtual channel name that you assign to the instrument in the Configuration Utility. Virtual channel names are aliases for instrument-specific channel strings. The instrument-specific channel strings can differ from one instrument to another. Virtual channel names allow you to use and swap instruments without having to change the channel names in your source code. You assign a virtual channel name to an instrument-specific channel through the Configuration Utility. This control accepts virtual channel names you have assigned to the specific instrument you are using. It also accepts the instrument-specific channel names. Default Value: "" Notes: (1) You can specify the channel name as a string variable or as a literal enclosed in double quotes. attributeid 26

31 ViAttr Pass the ID of an attribute. From the function panel window, you can use this control as follows. - Click on the control or press <ENTER>, <spacebar>, or <ctrl-down arrow>, to display a dialog box containing a hierarchical list of the available attributes. Attributes whose value cannot be set are dim. Help text is shown for each attribute. Select an attribute by double-clicking on it or by selecting it and then pressing <ENTER>. Read-only attributes appear dim in the list box. If you select a read-only attribute, an error message appears. A ring control at the top of the dialog box allows you to see all IVI attributes or only the attributes of the ViString type. If you choose to see all IVI attributes, the data types appear to the right of the attribute names in the list box. Attributes with data types other than ViString are dim. If you select an attribute data type that is dim, LabWindows/CVI transfers you to the function panel for the corresponding function that is consistent with the data type. - If you want to enter a variable name, press <CTRL-T> to change this ring control to a manual input box. - If the attribute in this ring control has named constants as valid values, you can view the constants by moving to the Attribute Value control and pressing <ENTER>. attributevalue ViChar[] Return Value Pass the value which you want to verify as a valid value for the attribute. From the function panel window, you can use this control as follows. - If the attribute currently showing in the Attribute ID ring control has constants as valid values, you can view a list of the constants by pressing <ENTER> on this control. Select a value by double-clicking on it or by selecting it and then pressing <ENTER>. Note: Some of the values might not be valid depending on the current settings of the instrument session.

37 cilxs_clearerror Purpose ViStatus cilxs_clearerror (ViSession instrumenthandle); This function clears the error code and error description for the IVI session. If the user specifies a valid IVI session for the instrument handle parameter, this function clears the error information for the session. If the user passes VI_NULL for the Vi parameter, this function clears the error information for the current execution thread. If the Vi parameter is an invalid session, the function does nothing and returns an error. The function clears the error code by setting it to VI_SUCCESS. If the error description string is non-null, the function de-allocates the error description string and sets the address to VI_NULL. Maintaining the error information separately for each thread is useful if the user does not have a session handle to pass to the cilxs_geterror function, which occurs when a call to cilxs_init or cilxs_initwithoptions fails. Parameter List instrumenthandle ViSession The ViSession handle that you obtain from the cilxs_init or cilxs_initwithoptions function. The handle identifies a particular instrument session. Default Value: None Return Value Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. You examine the status code from each call to an instrument driver function to determine if an error occurred. To obtain a text description of the status code, call the cilxs_error_message function.
