Synopsis
Declared in <ball_categorymanager.h>
Category const*
setCategory(
CategoryHolder* categoryHolder,
char const* categoryName);Description
Add to this category registry a new category having the specified categoryName, possibly changed by the registered category name filter callback, and default threshold levels if (the possibly filtered) categoryName is not present in the registry and the number of categories in the registry is less than the registry capacity. Return the address of the (possibly newly‐created) non‐modifiable category having (the possibly filtered) categoryName, if such a category exists, and the address of the non‐modifiable Default Category otherwise. If the specified categoryHolder is non‐null, then also load into categoryHolder the returned category and its maximum level and link categoryHolder to the category if it has not yet been linked. The behavior is undefined unless categoryName is null‐terminated. Note that a valid category address is always returned.
Return Value
address of the category named categoryName, or of the Default Category if none exists
