query_mq_error_handler()

static void query_mq_error_handler ( void *  cls, enum GNUNET_MQ_Error  error  )

static

Generic error handler, called with the appropriate error code and the same closure specified at the creation of the message queue.

Not every message queue implementation supports an error handler.

Parameters

cls	closure with the struct GNUNET_NSE_Handle *
error	error code
