GpaStatus GpaRegisterLoggingCallback(
GpaLoggingType logging_type,
GpaLoggingCallbackPtrType callback_func_ptr);
Description
Registers a callback function to receive log messages. Only one callback function can be registered, so the implementation should be able to handle the different types of messages. A parameter to the callback function will indicate the message type being received. Messages will not contain a newline character at the end of the message. To unregister a callback function, specify kGpaLoggingNone for the logging_type and NULL for the callback_func_ptr.
