在执行结束时执行操作

Question

I have an http server (launched using http.Handle) and I would like to do some operations.

How can I do that (on linux) ? Is it possible to do those operations in case of a ctrl-C ?

I'm not familiar with unix signals so the answer may be trivial.

Answer 1

You can subscribe to the TERM and INT signals using the signal package. But note that these signals are only sent when the process is killed explicitly; normal exit (initiated by the process itself) does not involve any sort of signals. I think for normal exit just do something in the main routine (which supposedly should spawn worker goroutines and then wait on them).

Read man 7 signal for more general info on POSIX signals.
