| 14 """ Library to implement a well-behaved Unix daemon process. | |
| 15 | |
| 16 This library implements the well-behaved daemon specification of | |
| 17 :pep:`3143`, “Standard daemon process library”. | |
| 18 | |
| 19 A well-behaved Unix daemon process is tricky to get right, but the | |
| 20 required steps are much the same for every daemon program. A | |
| 21 `DaemonContext` instance holds the behaviour and configured | |
| 22 process environment for the program; use the instance as a context | |
| 23 manager to enter a daemon state. | |
| 24 | |
| 25 Simple example of usage:: | |
| 26 | |
| 27 import daemon | |
| 28 | |
| 29 from spam import do_main_program | |
| 30 | |
| 31 with daemon.DaemonContext(): | |
| 32 do_main_program() | |
| 33 | |
| 34 Customisation of the steps to become a daemon is available by | |
| 35 setting options on the `DaemonContext` instance; see the | |
| 36 documentation for that class for each option. | |
