Load into the specified holder the address of the specified category, its enabled status, and the address of the next holder in the linked list of category holders maintained by category (prepending holder to the linked list of category holders for category). The supplied category will update the value returned by holder->enabled() when its enabled state changes, and will reset holder (i.e., holder->reset()) when category is destroyed. The behavior is undefined unless holder remains valid and unmodified (by the client) for the lifetime of this object.

registerCategoryHolder(
