delete (MathScript RT Module Function)
Owning Class: support
Requires: MathScript RT Module
Syntax
delete(filename)
delete(obj)
Description
Deletes a file or a plot object. delete(filename) deletes the file you specify in filename. delete(obj) deletes a plot object and removes the object from the Variable List in the LabVIEW MathScript Window.
Inputs
| Name | Description |
|---|---|
| filename | Specifies the path to the file you want to delete. If filename is a relative path, LabVIEW begins searching for the file in the current working directory. filename can include the wildcards ? and *. filename is a string. |
| obj | Specifies the reference to the plot object you want to delete. Plot objects include line, plot area, plot window, and text objects. If obj is a line object or a text object, this function removes the object from the plot area. If obj is a plot area object, this function clears the plot area. If obj is a plot window object, this function closes the plot window. |
Details
If you use this function in a stand-alone application or shared library and filename is a relative path, LabVIEW searches for the file in the path where you installed the application or shared library. If filename is an absolute path, LabVIEW searches for the file on the local machine or target at the specified location. (Real-Time Module) If you deploy this function to an RT target and filename is a relative path, LabVIEW searches for the file in the path returned by the Default Data Directory VI.
This function is not supported in the LabVIEW Run-Time Engine if you use the delete(obj) syntax. This syntax can remain in your scripts when you build a stand-alone application or shared library, but the LabVIEW Run-Time Engine does not execute this function.
Examples
fid = fopen('filename.txt', 'a');
fclose(fid);
delete('filename.txt')
