## nng_stat_string

Get statistic string value.

### Synopsis

```c
#include <nng/nng.h>

typedef struct nng_stat nng_stat;

const char *nng_stat_string(nng_stat *stat);
```

### Description

The `nng_stat_string` function returns a string value for the statistic _stat_, which must be of type `NNG_STAT_STRING` (see xref:nng_stat_type.adoc[`nng_stat_type`]).

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

NOTE: The returned string is valid until xref:nng_stats_free.adoc[`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.
