#define DL | ( | X | ) |
#define EL | ( | X | ) |
A macro for writing error message to the Logger.
#define LOGGER ASSA::Logger::get_instance() |
#define trace | ( | s | ) | ASSA::DiagnosticContext tRaCeR(s); |
trace() is used to trace function call chain in C++ program.
trace() logs a message of type [function_name] –v– with log level TRACE, where 'function_name' is the argument supplied. Upon exiting from the function, record [function_name] –^– is written to the log file.
Application user can easily turn trace on/off by supplying different debug mask with {'-m', '–mask'} command-line argument and masking out highest bit in debug mask: TRACE
#define trace_with_mask | ( | s, | |
m | |||
) | ASSA::DiagnosticContext tRaCeR(s, m); |
trace_with_mask() is used to trace function call chain in C++ program.
Mask is used to limit the scope of the messages.
