Return or create the named category in the logger manager registry.
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.
