◆ callWrapperAsync()

void llvm::orc::SelfExecutorProcessControl::callWrapperAsync	(	ExecutorAddr	WrapperFnAddr,
		IncomingWFRHandler	OnComplete,
		ArrayRef< char >	ArgBuffer )

overridevirtual

Run a wrapper function in the executor.

The given WFRHandler will be called on the result when it is returned.

The wrapper function should be callable as:

CWrapperFunctionBuffer fn(uint8_t *Data, uint64_t Size);

◆ Create()

Expected< std::unique_ptr< SelfExecutorProcessControl > > llvm::orc::SelfExecutorProcessControl::Create	(	std::shared_ptr< SymbolStringPool >	SSP = nullptr,
		std::unique_ptr< TaskDispatcher >	D = nullptr )

static

Create a SelfExecutorProcessControl with the given symbol string pool and memory manager.

If no symbol string pool is given then one will be created. If no memory manager is given a jitlink::InProcessMemoryManager will be created and used by default.
