Detailed Description

Builtin Transport Plugin for Intra-Process Communications.

Messages are sent using local memory, with only 1 copy in send path, and no copy on the receive path, which yields the fastest possible critical send while still maintaining the architectural decoupling of the higher layers of NDDS from implementations of NDDS_Transport_Plugin.

The transport plugin has exactly one "receive interface"; and since the address_bit_count is 0; it can be assigned any address. Thus the interface is located by the "network address" associated with the transport plugin.

Function Documentation

NDDS_Transport_Plugin* NDDS_Transport_Intra_new

(

const struct NDDS_Transport_Intra_Property_t *

property_in

)

Create a new intra process transport.

An application may create multiple intra process, possibly for use in different domains. If so, they are completely independent of each other.

Parameters

property_in

<<in>> Desired behavior of this transport. May be NULL for default property. The transport plugin can only support one unicast receive interface; therefore the interface selection lists are ignored.

Returns

handle to a Intra-process Transport Plugin on success

NULL on failure.
