Logging

The NVDIA^® DriveWorks library implements simple logging, by passing a log message to a user-specified callback.

To initialize a logger instance, pass a callback method to the logger initialization. The call must occur before SDK context initialization. For more information, see Core Logger.

// initialize global logger instance to push all logs to the given callback
dwLogger_initialize(myLoggerCallback());

// log everything above WARN level, i.e. WARN and ERROR
dwLogger_setLogLevel(DW_LOG_WARN);

dwContextParameters sdkParams = {};
dwVersion sdkVersion;
dwGetVersion(&sdkVersion);
dwInitialize(&sdk, sdkVersion, &sdkParams);

Note

Currently, logger is a global instance and is not bound to a specific SDK context.

A callback method that accepts log messages has the following syntax:

void myLoggerCallback(dwContextHandle_t context, dwLoggerVerbosity type, const char* msg)
{
   ...
}
