Starting and stopping

This chapter describes how to start and stop the Gun application.

Setting up

Specify Gun as a dependency to your application in your favorite build tool.

With Erlang.mk this is done by adding gun to the DEPS variable in your Makefile.

Adding Gun as an Erlang.mk dependency

DEPS = gun

Starting

Gun is an OTP application. It needs to be started before you can use it.

Starting Gun in an Erlang shell

1> application:ensure_all_started(gun).
{ok,[crypto,cowlib,asn1,public_key,ssl,gun]}

Stopping

You can stop Gun using the application:stop/1 function, however only Gun will be stopped. This is the reverse of application:start/1. The application_ensure_all_started/1 function has no equivalent for stopping all applications.

Stopping Gun

application:stop(gun).
