userData QosPolicy constraint

Hi

We want to define the idl with the user data (@copy). but meet to the userData constraint, that say the total of userData character into the IDL can not be more than 255 character.

How can set the "DDS_DomainParticipantQos.resource_limits.reader_user_data_max_length" ?

In the following example we get the corresponding error (the total of character can not be more than 255 character)

Usage of UserData Qos Policy for DataReader

Hello All,

I am trying to use the UserData QoS Policy of DataReader.

For that I have done the following changes:

1) Creation of Subscriber and DataReader of DDS_Builtintopic_Subscription type (Topic name is "DCPSSubscription")

2) Using the Example Builtin topics application for Subcribing to this "DCPSSubscription" topic

3) When a DataReader is created in the domain, I am able to receive the notification that a node has joined.
