Usage

If the statistic is not of type NNG_STAT_STRING, then NULL will be returned.

The returned string is valid until nng_stats_free() is called to free the memory for the snapshot.

Return values

The string value associated with stat, or NULL if the statistic is not a string type.

Errors

None.
