note_publish()

void pulp::dataplane::PublishCounter::note_publish ( )

inlinenoexceptinherited

Writer (audio/host) thread, from publish().

Relaxed: the counter orders no other memory, it only has to be monotonic and eventually visible.

publish()

void pulp::dataplane::ScalarSource::publish

(

float

value

)

Publish the latest value from the writer (audio/host) thread.

publish_seq()

std::uint32_t pulp::dataplane::PublishCounter::publish_seq ( ) const

inlinenoexceptinherited

Reader (UI) thread. Changes iff the writer published since the last read.

read()

float pulp::dataplane::ScalarSource::read

(

)

Read the latest value from the reader (UI) thread.
