- @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.
