Obtain Notifier

Returns a reference to a notifier. Use this reference when calling other Notifier Operations functions. Details

name contains the name of the notifier that you want to obtain or create. The default is an empty string to create an unnamed notifier.
element data type is the type of data that you want the notifier to contain. You can wire any data type to this input.
create if not found? specifies whether you want to create a new notifier if one with the same name as name does not exist. If TRUE (default), the function creates a notifier if one with the same name does not exist.
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.
notifier out is a reference to the existing named notifier or the new notifier created by this function.
created new? is TRUE if the function created a new notifier.
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.

Obtain Notifier Details

Use named notifiers to pass data between two sections of a block diagram or between two VIs. If you do not wire name, the function creates a new, unnamed notifier reference. If you wire name, the function first searches for an existing notifier with the same name and returns its reference if it exists. If a notifier with the same name does not already exist and create if not found? is TRUE, the function creates a new, named notifier reference.

This function might return error codes 1, 2, 1094, or 1100.
