BloombergLP::balm::MetricsManager::addSpecificPublisher

Add the specified publisher to the set of publishers that will be used to publish metrics for the category identified by the specified categoryName. Return 0 on success, and a non-zero value with no effect if publisher has already been registered to publish the identified category. The behavior is undefined unless categoryName is null-terminated. Note that this method will fail and return a non-zero value if publisher has previously been registered to publish every category (using the alternative addGeneralPublisher method).
