Synopsis
When registering an add-on function in a DLL (via the RXFUNCADD() built-in function), the DLL had an error loading. Reginald therefore triggered the FAILURE condition. (So, you can trap errors associated with RXFUNCADD() by trapping FAILURE). name is the name of the DLL that didn't load.
You can retrieve a more informative error message using the RXFUNCERRMSG() built-in function after RXFUNCADD() fails.
