# lwres\_inetntop(3)

lightweight resolver IP address presentation

## NAME

lwres\_net\_ntop - lightweight resolver IP address presentation

## SYNOPSIS

```
#include <lwres/net.h>
```

**const char \* lwres\_net\_ntop(int** *af***, const void \****src***, char \****dst***, size\_t** *size***);**

## DESCRIPTION

**lwres\_net\_ntop()** converts an IP address of protocol family *af* — IPv4 or IPv6 — at location *src* from network format to its conventional representation as a string. For IPv4 addresses, that string would be a dotted-decimal. An IPv6 address would be represented in colon notation as described in RFC1884.

The generated string is copied to *dst* provided *size* indicates it is long enough to store the ASCII representation of the address.

## RETURN VALUES

If successful, the function returns *dst*: a pointer to a string containing the presentation format of the address. **lwres\_net\_ntop()** returns **NULL** and sets the global variable **errno** to **EAFNOSUPPORT** if the protocol family given in *af* is not supported.

## SEE ALSO

**RFC1884**(), [**inet\_ntop**(3)](/inet_ntop/3.md), [**errno**(3)](/errno/3.md).
