AddValueObject()

uint32_t Materializer::AddValueObject	(	ConstString	name,
		ValueObjectProviderTy	valobj_provider,
		Status &	err
	)

Create entity from supplied ValueObject and count it as a member of the materialized struct.

Behaviour is undefined if 'valobj_provider' is empty.

Parameters

[in]	name	Name of variable to materialize
[in]	valobj_provider	When materializing values multiple times, this callback gets used to fetch a fresh ValueObject corresponding to the supplied frame. This is mainly used for conditional breakpoints that re-apply an expression whatever the frame happens to be when the breakpoint got hit.
[out]	err	Error status that gets set on error.

Returns

Offset in bytes of the member we just added to the materialized struct.
