# nng\_stat\_string(3)

get statistic string value

## NAME

nng\_stat\_string - get statistic string value

## SYNOPSIS

```
#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 `nng_stat_type(3)`).

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

**Note**\

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.
