Detailed Description

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.
