FreeAndNil
Free object if needed, and set object reference to Nil
Declaration
Source position: sysutilh.inc line 330
procedure FreeAndNil(var obj);
Description
FreeAndNil will free the object in Obj and will set the reference in Obj to Nil. The reference is set to Nil first, so if an exception occurs in the destructor of the object, the reference will be Nil anyway.
Errors
Exceptions that occur during the destruction of Obj are not caught.
