How can I use APIs in dds::core::cond::StatusCondition? [13601]

[weithegreat]

Hey folks, I'm new to fastDDS. I saw that we have both include/dds and include/fastdds/ however include/dds directory is not installed when I install fastDDS.
There;re APIs in include/dds/core/cond/Condition.hpp I want to use, like handler, but it's not in include/fastdds/dds/core/condition/Condition.hpp

I was wondering why do we have these two directories? Is include/dds/core/cond/Condition.hpp not supposed to be used?

Sorry for the late reply, @weigewansui,

The API included in the include/dds API is not installed because it is still under development. The OMG DDS Specification defines a PIM (Platform Independent Model) and a PSM (Platform Specific Model) APIs. Currently, Fast DDS only has implemented the PIM API and the PSM API (under the dds folder) is still being developed and thus it is not possible to use it yet.

However, you are probably interested on using the StatusCondition API and I am glad to say that this feature is available in the PIM API (the one already available to the users) since release 2.4.0 (last September 2021)!
