If the VI name begins with a non-alphanumeric character, the LabVIEW C Code Generator prepends A_ to the beginning of the C function name. This VI Server call also generates the following header files when a user builds an embedded VI into an embedded application. • LVForms.h contains...
TestStand unescapes the string before passing it to the VI and substitutes the correct character values for the hexadecimal values in the escaped string. Calling VIs with Cluster Parameters When you configure calls to VIs that use clusters as parameters, you can specify that each cluster element ...
