read/take with n parameter (CON-25)

[ilya1725]

Several examples (in Python) presented in this repository use either read and take functions. Generally, those functions will absorb all samples in the queue. Is there a way to use something like take_next_sample? Or perhaps use read, but then extract from the list of samples the ones that weren't read before?

Hello @ilya1725 ,

You are right: right now we call take or read passing max_sample = DDS_LENGTH_UNLIMITED. We could expose a take(n) and a read(n) that would allow the user to specify max_sample.

Would that work for your use case?

[ilya1725]

yes, it will.
