:mrdocs:

Initialize the logger manager singleton with the specified `singleton`. Optionally specify an `adoptSingleton` flag indicating whether this method takes ownership of `singleton`, in which case `shutDownSingleton` will destroy `singleton`. If `adoptSingleton` is not specified, this method does _not_ take ownership of `singleton` (and `shutDownSingleton` will not destroy it). Return 0 if the logger manager singleton was successfully initialized, and a non‐zero value otherwise. This method has no effect (aside from logging a warning) if the logger manager singleton already exists, in which case this method does _not_ take ownership of `singleton` regardless of the value of `adoptSingleton`. Note that this version of `initSingleton` is meant for use _only_ on Windows to initialize another dynamically loaded copy of the `LoggerManager` system. Also note that a suitable singleton may be obtained by calling `createLoggerManager`, or from the `singleton` class method of an already‐initialized `LoggerManager` system.
