Log levels

Log levels for the libraries in this SDK.

Each library should specify a log level by setting LIBRARY_LOG_LEVEL. All log messages with a level at or below the specified level will be printed for that library.

Currently, there are 4 log levels. In the order of lowest to highest, they are:

• IOT_LOG_NONE
  No log messages.
• IOT_LOG_ERROR
  Only critical, unrecoverable errors.
• IOT_LOG_WARN
  Message about an abnormal but recoverable event.
• IOT_LOG_INFO
  A helpful, informational message.
• IOT_LOG_DEBUG
  Detailed and excessive debug information.
