inet_ntop - convert IPv4 and IPv6 addresses from binary to text form
#include <arpa/inet.h> const char *inet_ntop(int af, const void *src, char *dst, socklen_t size);
This function converts the network address structure
src in the
af address family into a character string. The resulting string is copied to the buffer pointed to by
dst, which must be a non-null pointer. The caller specifies the number of bytes available in this buffer in the argument
inet_ntop() extends the inet_ntoa(3) function to support multiple address families, inet_ntoa(3) is now considered to be deprecated in favor of inet_ntop(). The following address families are currently supported:
src points to a
struct in_addr (in network byte order) which is converted to an IPv4 network address in the dotted-decimal format, "
ddd.ddd.ddd.ddd". The buffer
dst must be at least INET_ADDRSTRLEN bytes long.
src points to a
struct in6_addr (in network byte order) which is converted to a representation of this address in the most appropriate IPv6 network address format for this address. The buffer
dst must be at least INET6_ADDRSTRLEN bytes long.
On success, inet_ntop() returns a non-null pointer to
dst. NULL is returned if there was an error, with
errno set to indicate the error.
af was not a valid address family.
The converted address string would exceed the size given by
