+# nng_log_level
+
+## NAME
+
+nng_log_level --- severity level for logging messages
+
+## SYNOPSIS
+
+```c
+#include <nng/nng.h>
+
+typedef enum nng_log_level {
+	NNG_LOG_NONE   = 0, // used for filters only, NNG suppresses these
+	NNG_LOG_ERR    = 3,
+	NNG_LOG_WARN   = 4,
+	NNG_LOG_NOTICE = 5,
+	NNG_LOG_INFO   = 6,
+	NNG_LOG_DEBUG  = 7
+} nng_log_level;
+
+void nng_log_set_level(nng_log_level level);
+nng_log_level nng_log_get_level(void);
+```
+
+## DESCRIPTION
+
+The `nng_log_level` type represents a severity for logged messages.
+These levels correspond to those found in the UNIX `syslog` subsystem,
+although applications should not depend upon the values being identical.
+
+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.
+
+The `nng_log_get_level` function returns the current log level, which can be useful
+to elide processing to create log content that will simply be discarded anyway.
