Publication Example

/* Foo_publisher.cxx

A publication of data of type MyOtherType

This file is derived from code automatically generated by the rtiddsgen 
command:

rtiddsgen -language C++11 -example <arch> Foo.idl

Example publication of type MyOtherType automatically generated by 
'rtiddsgen'. To test them follow these steps:

(1) Compile this file and the example subscription.

(2) Start the subscription on the same domain used for RTI Data Distribution
Service with the command
objs/<arch>/Foo_subscriber <domain_id> <sample_count>

(3) Start the publication on the same domain used for RTI Data Distribution
Service with the command
objs/<arch>/Foo_publisher <domain_id> <sample_count>

(4) [Optional] Specify the list of discovery initial peers and 
multicast receive addresses via an environment variable or a file 
(in the current working directory) called NDDS_DISCOVERY_PEERS. 

You can run any number of publishers and subscribers programs, and can 
add and remove them dynamically from the domain.

Example:

To run the example application on domain <domain_id>:

On Unix: 

objs/<arch>/Foo_publisher <domain_id> 
objs/<arch>/Foo_subscriber <domain_id> 

On Windows:

objs<arch>\Foo_publisher <domain_id>  
objs<arch>\Foo_subscriber <domain_id>
