The daemon-windows file is missing a `set_detach` routine, so add it. This will be useful in the long run. Signed-off-by: Alin Gabriel Serdean <aserdean@ovn.org> Acked-by: Ben Pfaff <blp@ovn.org> Acked-by: Anand Kumar <kumaranand@vmware.com>

/* This file provides an interface for utilities to run in the background
|
|
* as daemons on POSIX platforms like Linux or as services on Windows platform.
|
|
* Some of the functionalities defined in this file are only applicable to
|
|
* POSIX platforms and some are applicable only on Windows. As such, the
|
|
* function definitions unique to each platform are separated out with
|
|
* ifdef macros. More descriptive comments on individual functions are provided
|
|
* in daemon-unix.c (for POSIX platforms) and daemon-windows.c (for Windows).
|
|
|
|
* The DAEMON_OPTION_ENUMS, DAEMON_LONG_OPTIONS and DAEMON_OPTION_HANDLERS
|
|
* macros are useful for parsing command-line options in individual utilities.
|
|
* For e.g., the command-line option "--monitor" is recognized on Linux
|
|
* and results in calling the daemon_set_monitor() function. The same option is
|
|
* not recognized on Windows platform.
