CallPointerConstructor

Call a constructor with a pointer argument.

Declaration

Source position: objects.pp line 589

function CallPointerConstructor(

  Ctor: codepointer;

  Obj: pointer;

  VMT: pointer;

  Param1: pointer

):pointer;

Description

CallVoidConstructor calls the constructor of an object. Ctor is the address of the constructor, Obj is a pointer to the instance. If it is Nil, then a new instance is allocated. VMT is a pointer to the object's VMT. Param1 is passed to the constructor. The return value is a pointer to the instance.

Note that this can only be used on constructors that require a pointer as the sole argument. It can also be used to call a constructor with a single argument by reference.

Errors

If the constructor expects other arguments than a pointer, the stack may be corrupted.
