:relfileprefix: ../../../
:mrdocs:

Add to the category registry of this logger manager a new category having the specified `categoryName` and `recordLevel`, `passLevel`, `triggerLevel`, and `triggerAllLevel` threshold levels, respectively, if (1) `categoryName` is not present in the registry, (2) the number of categories in the registry is less than the registry capacity, and (3) `recordLevel`, `passLevel`, `triggerLevel`, and `triggerAllLevel` are all within the range `[0 .. 255]`. If `categoryName` is already present and each threshold level is within the valid range then reset the threshold levels of `categoryName` to the specified values. Return the address of the (possibly newly‐created) modifiable category having `categoryName` if `categoryName` was either created or its thresholds reset, and 0 otherwise. The behavior is undefined unless `categoryName` is null‐terminated. Note that 0, and _not_ the _Default_ _Category_, is returned on failure.
