- /// unit
- ///
- /// !Purpose
- ///
- /// Standard output methods for reporting debug information, warnings and
- /// errors, which can be easily be turned on/off.
- ///
- /// !Usage
- /// -# Initialize the DBGU using TRACE_CONFIGURE() if you intend to eventually
- /// disable ALL traces; otherwise use DBGU_Configure().
- /// -# Uses the TRACE_DEBUG(), TRACE_INFO(), TRACE_WARNING(), TRACE_ERROR()
- /// TRACE_FATAL() macros to output traces throughout the program.
- /// -# Each type of trace has a level : Debug 5, Info 4, Warning 3, Error 2
- /// and Fatal 1. Disable a group of traces by changing the value of
- /// TRACE_LEVEL during compilation; traces with a level bigger than TRACE_LEVEL
- /// are not generated. To generate no trace, use the reserved value 0.
- /// -# Trace disabling can be static or dynamic. If dynamic disabling is selected
- /// the trace level can be modified in runtime. If static disabling is selected
- /// the disabled traces are not compiled.
- ///
- /// !Trace level description
- /// -# TRACE_DEBUG (5): Traces whose only purpose is for debugging the program,
- /// and which do not produce meaningful information otherwise.
- /// -# TRACE_INFO (4): Informational trace about the program execution. Should
- /// enable the user to see the execution flow.
- /// -# TRACE_WARNING (3): Indicates that a minor error has happened. In most case
- /// it can be discarded safely; it may even be expected.
- /// -# TRACE_ERROR (2): Indicates an error which may not stop the program execution,
- /// but which indicates there is a problem with the code.
- /// -# TRACE_FATAL (1): Indicates a major error which prevents the program from going
- /// any further.
