Detailed Description

template<typename ShareDataType, typename MsgType>
class SST::Core::Interprocess::IPCTunnel< ShareDataType, MsgType >

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
