+/** @file
+ @ingroup common_src
+
+ @brief Real-time safe event trace logging facility for debugging.
+
+ Allows data to be logged to a fixed size trace buffer in a real-time
+ execution context (such as at interrupt time). Each log entry consists
+ of a message comprising a string pointer and an int.  The trace buffer
+ may be dumped to stdout later.
+
+ This facility is only active if PA_TRACE_REALTIME_EVENTS is set to 1,
+ otherwise the trace functions expand to no-ops.
+
+ @fn PaUtil_ResetTraceMessages
+ @brief Clear the trace buffer.
+
+ @fn PaUtil_AddTraceMessage
+ @brief Add a message to the trace buffer. A message consists of string and an int.
+ @param msg The string pointer must remain valid until PaUtil_DumpTraceMessages
+    is called. As a result, usually only string literals should be passed as
+    the msg parameter.
+
+ @fn PaUtil_DumpTraceMessages
+ @brief Print all messages in the trace buffer to stdout and clear the trace buffer.
