User Defined Functions - Functions and Parameters

153.1k

User-Defined Basic Functions A user-defined function in its most basic form is one that does not require any parameters to fulfil its work. The calling script or user-defined function does not receive any values from these functions. A "void" function is the name given to this type of function.

User-defined functions are functions that you employ in the body of a policy to arrange your code. You can call a function the same way you call the built-in action and parser functions once you've defined it. Variables supplied to a function are referenced rather than passed by value.

In a scenario where the conventional assumption is that functions are built into the programme or environment, a user-defined function (UDF) is a function provided by the user of the programme or environment. UDFs are often written to meet the needs of their creator.

User-defined functions allow programmers to create their own routines and procedures that the computer can follow; they are the fundamental building block of any programme and are also critical for modularity and code reuse because a programmer can create a user-defined function that performs a specific task and simply call it.
