Detailed Description

System logging header OpenWSN definitions.

This header implements the same functionality as log.h but avoiding macro redefinitions with OpenWSN LOG_% functions.

Enumeration Type Documentation

◆ anonymous enum

anonymous enum

defined log levels

These are the logging levels a user can choose. The idea is to set LOG_LEVEL to one of these values in the application's Makefile. That will restrict output of log statements to those with equal or lower log level.

The default log level is LOG_INFO, which will print every message.

The log function calls of filtered messages will be optimized out at compile time, so a lower log level might result in smaller code size.

Enumerator
LOG_NONE 

Lowest log level, will output nothing.

LOG_ERROR 

Error log level, will print only critical, non-recoverable errors like hardware initialization failures.

LOG_WARNING 

Warning log level, will print warning messages for temporary errors.

LOG_INFO 

Informational log level, will print purely informational messages like successful system bootup, network link state, ...

LOG_DEBUG 

Debug log level, printing developer stuff considered too verbose for production use.

LOG_ALL 

print everything
