## DESCRIPTION

The `nng_log_set_level` function is used to set the minimum severity to *level* for processing log messages. Any messages with a less severe rating are not processed and simply are discarded. Use `NNG_LOG_NONE` to suppress all log messages. Use `NNG_LOG_DEBUG` to receive all log messages.
