Details

If you use this function in a stand-alone application or shared library and file is a relative path, LabVIEW searches for the file in the path where you installed the application or shared library. If file 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 file is a relative path, LabVIEW searches for the file in the path returned by the Default Data Directory VI.

The following table lists the support characteristics of this function.

Supported in the LabVIEW Run-Time Engine Yes
Supported on RT targets Yes
Suitable for bounded execution times on RT No (affects entire script)

Examples

In the following example, LabVIEW creates test.csv in the LabVIEW Data directory. LabVIEW then reads the values in test.csv and returns these values as a matrix.

fwrite_csv('test', magic(5), 2, 2);
a = fread_csv('test', 'A2..C3')
