inet_ntop() -- convert address from network format to presentation format

SYNOPSIS

#include <arpa/inet.h>

char *inet_ ntop(int af, const void *src, char *dst, size_t size);

DESCRIPTION

The inet_ntop() function converts an address from network format (usually a struct in_addr, struct in6_addr, or some other binary form, in network byte order) to presentation format.

PARAMETERS

af: Specifies the address family. Currently, only AF_INET and AF_INET6 are supported.
src: Points to the address. The format of the address is interpreted according to af.
dst: Points to the buffer where the converted address is stored.
size: Is the size of dst, in bytes.

RETURN VALUES

On success, the inet_ntop() function returns dst on success. Otherwise, it returns a null pointer, and sets errno to one of the following:

EAFNOSUPPORT: The address family specified in af is not supported by this function.
ENOSPC: The buffer specified by dst and size is not large enough to contain the converted address.
