convert address from network format to presentation format 

Function

SYNOPSIS

#include <arpa/inet.h>

const 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.
