Detailed Description

Tunneling class between two processes, connected by shared memory.

Supports multiple circular-buffer queues, and a generic region of memory for shared data.

Template Parameters

ShareDataType	Type to put in the shared data region
MsgType	Type of messages being sent in the circular buffers

Constructor & Destructor Documentation

template<typename ShareDataType , typename MsgType >

SST::Core::Interprocess::IPCTunnel< ShareDataType, MsgType >::IPCTunnel	(	uint32_t	comp_id,
		size_t	numBuffers,
		size_t	bufferSize,
		uint32_t	expectedChildren = `1`
	)

inline

Construct a new Tunnel for IPC Communications.

Parameters

comp_id	Component ID of owner
numBuffers	Number of buffers for which we should tunnel
bufferSize	How large each core's buffer should be

template<typename ShareDataType , typename MsgType >

SST::Core::Interprocess::IPCTunnel< ShareDataType, MsgType >::IPCTunnel ( const std::string & region_name )

inline

Access an existing Tunnel.

Parameters

region_name Name of the shared-memory region to access
