:mrdocs:

Load into the specified `categoryHolder` the address of the non‐modifiable category having the specified `categoryName` if such a category exists, or if a new category having `categoryName` can be added to the registry (i.e., if the registry has sufficient capacity to accommodate new entries); otherwise, load the address of the non‐modifiable _Default_ _Category_. Also load into `categoryHolder` the maximum threshold level of the category ultimately loaded into `categoryHolder`. This method has no effect if the logger manager singleton is not initialized.
