integer_to_handle — Convert an integer into a handle.
It is not recommended to use this operator in HDevelop. This operator is only provided for reasons of backward compatibility.
integer_to_handle( : : IntegerHandle : Handle)
integer_to_handle converts the integer IntegerHandle, that
represents a handle, to a handle of type HANDLE_PAR and returns it in
Handle.
This allows to convert handles created in code parts where the legacy handle
mode is enabled into proper handles.
If the legacy handle mode is disabled (the default), the ownership of the handle
is transferred onto the handle. In this case, the handle will automatically
be cleared once all references to that handle, such as in the tuple
Handle, are overwritten.
In that case, if the original IntegerHandle should continue to be
used, a reference to the returned Handle must
be kept in order to avoid clearing the handle.
If the legacy handle mode is enabled, the returned value will again
be an integer. Additionally, the handle must then be cleared using
clear_handle or the clear operator of the corresponding semantic
type of the handle.
It is not recommended to use this operator in HDevelop. This operator is solely provided to enable backward compatibility with legacy code.
This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
IntegerHandle (input_control) pointer(-array) → (integer)
The handle as integer.
Handle (output_control) handle(-array) → (handle)
The handle as handle.
If the parameters are valid, the operator integer_to_handle
returns the value 2 (H_MSG_TRUE). Otherwise, an exception is raised.
