C HTTP流服务器以流音频分贝级别

Question

Hi I have written a decibel level meter in C which reads Linux alsa constantly and output decibel levels numbers in STDOUT.

Now I would like to view via HTTP and streaming live data to clients, with proper js+html decoration, it behaves as a noise meter, with graph and needles.

Therefore I would like to know if some one can point me direction integrate them into a HTTP streaming server able to server multiple clients in real time.

You can use several C libraries. Some C libraries provide HTTP server abilities, eg libonion or libmicrohttpd . Other libraries provide HTTP client abilities, eg libcurl

All are using some event loop, eg libev , libevent or at least some multiplexing syscall like poll(2)

You could also make your application a FASTCGI app.
