Synchronous concurrency: Difference between revisions

The ''state'' argument is the agent's state at the start of the call, and the last expression becomes the agent's new state.

 

 

(def writer (agent 0))

The reader executes on the main thread. It passes each line to the writer -- the ''send'' call returns immediately, waits until the writer has finished writing all the lines, gets the line count & prints it, and terminates the writer.

 

(send writer write-line line))

(await writer)
