/**
 * @brief ROCProfiler External Correlation ID Operations.
 *
 * These kinds correspond to callback and buffered tracing kinds (@see
 * ::rocprofiler_callback_tracing_kind_t and ::rocprofiler_buffer_tracing_kind_t) which generate
 * correlation IDs. Typically, rocprofiler-sdk uses the most recent external correlation ID on the
 * current thread set via ::rocprofiler_push_external_correlation_id; however, this approach can be
 * problematic if a new external correlation ID should be set before the
 * ::ROCPROFILER_CALLBACK_PHASE_ENTER callback or if relevant external correlation IDs are desired
 * when the buffered tracing is used. Thus, rocprofiler-sdk provides a way for tools to get a
 * callback whenever an external correlation ID is needed. However, this can add significant
 * overhead for those who only need these callbacks for, say, kernel dispatches while the HSA API is
 * being traced (i.e. lots of callbacks for HSA API functions). The enumeration below is provided to
 * ensure that tools can default to using the external correlation IDs set via the push/pop methods
 * where the external correlation ID value is not important while also getting a request for an
 * external correlation ID for other tracing kinds.
