is_struct

This function can be used to check and see if a variable holds a struct (it will return true) or not (in which case it will return false).

Syntax:

is_struct(n);

Returns:

Boolean

Example:

if is_struct(a)
    {
    delete(a);
    }

The above code checks a variable to see if it is a struct, and if the function returns true, the struct is deleted.
