Function Names
nullSynopsis
null ( parameters ... );Description
This function does nothing, but is otherwise useful:
- As it accepts any number and type of parameters, it is automatically used as a placeholder function in case the original function name is not found but the code should not run (e.g. false condition inside an if(…) block).
- Temporary placeholder for any other function to choose
- Easy way to get obtain a 'void' value if needed.
- Hidden to the programmer, it is used to parse over user-defined functions fast and efficiently.
