NAME

       inet_pton - Create a network address structure

SYNOPSIS

       #include <sys/types.h>
       #include <sys/socket.h>
       #include <arpa/inet.h>

       int inet_pton(int af, const char *src, void *dst);

DESCRIPTION

       This  function converts the character string src into a network address
       structure in the af address family, then  copies  the  network  address
       structure to dst.

       inet_pton(3)  extends  the  inet_addr(3)  function  to support multiple
       address families, inet_addr(3) is now considered to  be  deprecated  in
       favor  of  inet_pton(3).   The following address families are currently
       supported:

       AF_INET       src points to  a  character  string  containing  an  IPv4
                     network    address    in    the    dotted-quad    format,
                     "ddd.ddd.ddd.ddd".  The address is converted to a  struct
                     in_addr  and  copied  to dst, which must be sizeof(struct
                     in_addr) bytes long.

       AF_INET6      src points to  a  character  string  containing  an  IPv6
                     network  address in any allowed IPv6 address format.  The
                     address is converted to a struct in6_addr and  copied  to
                     dst, which must be sizeof(struct in6_addr) bytes long.

       Certain  legacy  hex  and  octal  formats  of AF_INET addresses are not
       supported by inet_pton, which rejects them.

RETURN VALUES

       inet_pton returns a negative value and sets errno to EAFNOSUPPORT if af
       does not contain a valid address family.  0 is returned if src does not
       contain a character string representing a valid network address in  the
       specified  address family.  A positive value is returned if the network
       address was succesfully converted.

BUGS

       AF_INET6 does not recognize IPv4 addresses.   An  explicit  IPv6-mapped
       IPv4 address must be supplied in src instead.
