Method: Daemons.run_proc

Defined in:
lib/daemons.rb

.run_proc(app_name, options = {}, &block) ⇒ Object

Passes control to Daemons. This function does the same as Daemons.run except that not a script but a proc will be run as a daemon while this script provides command line options like ‘start’ or ‘stop’ and the whole pid-file management to control the proc.

app_name

The name of the application. This will be used to contruct the name of the pid files and log files. Defaults to the basename of the script.

options

A hash that may contain one or more of the options listed in the documentation for Daemons.run

A block must be given to this function. The block will be used as the :proc entry in the options hash.

Example:

Daemons.run_proc('myproc.rb') do
  loop do
    accept_connection()
    read_request()
    send_response()
    close_connection()
  end
end
