Get Waveform Attribute

Retrieves the names and values of all attributes or if you specify the name of an attribute, retrieves the value of the specified attribute. Attributes can be the channel names. If the function does not find the specified attribute(s) or if it cannot convert the attribute to the default value, value is empty.

waveform is the waveform for which you want to retrieve an attribute(s).
name is the name of the attribute. Do not wire this parameter if you want to retrieve all the attributes associated with a waveform.
default value is the type of the attribute. You must wire this control to specify the type.
error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
code is the error or warning code. The default is 0. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
duplicate waveform is the waveform with new or replaced attribute.
found indicates if the attribute was found.
value is the value of the requested attribute. This is a polymorphic output that has the same type as default value.
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
code is the error or warning code. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
