:mrdocs:

Return from the logger manager singleton's category registry 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, return the address of the non‐modifiable _Default_ _Category_. Return 0 if the logger manager singleton is not initialized.
