New page

<pre>
UnsetFunction( <function-name> )
</pre>

=== Description ===

Delete a previous user defined function from Sputnik.

==== function-name ====

The function name to delete.

=== Return Value ===

Success: Returns 1.

Failure: Returns 0.

=== Remarks ===

This function is used to remove a previous added function to Sputnik for example if you have a plugin system that adds a series of functions you could make the plugin remove all functions when a command is typed.

Then you could load the plugin again basically allowing an update to your programs source code while it is still running.

=== Example ===

<syntaxhighlight lang="sputnik">
// Make a string containing text of a FUNCTION to load this string as Sputnik code later
my $Function = @"
Function Add2($a, $b)
{
return $a + $b;
}
";

// Load the function for the first time
// This will view the string as a peice of Sputnik code (same as include())
Eval($Function); // Bascially it will add the funciton "Add2" to Sputnik

// Call the function
println("1+2 Is: " . Add2(1, 2) );

// Now delete the function from Sputnik
UnsetFunction("Add2");

// Try call the function again
println("Lets try call it again");
println("1+2 Is: " . Add2(1, 2) ); // Notice the crash here?
// It crashes above because the funciton "Add2" no longer exists within Sputnik
