# lwres_inetntop

## 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.
