| 5 | JohnMcPherson | 14 | !!DESCRIPTION |
| 1 | perry | 15 | |
| 16 | |||
| 5 | JohnMcPherson | 17 | 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''. |

| 5 | JohnMcPherson | 20 | 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: |
| 1 | perry | 21 | |
| 5 | JohnMcPherson | 22 | ;__AF_INET__: ''src'' points to a character string containing an [IPv4] network address in the dotted-quad format, ''ddd.ddd.ddd.ddd'' ''struct in_addr'' and copied to ''dst,'' which must be ''sizeof(struct in_addr)'' bytes long. |
| 1 | perry | 23 | |
| 24 | |||
| 5 | JohnMcPherson | 25 | ;__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. |

| 27 | |||
| 5 | JohnMcPherson | 28 | Certain legacy hex and octal formats of __AF_INET__ addresses are not supported by ''inet_pton'', which rejects them. |
| 1 | perry | 29 | |
| 30 | !!RETURN VALUE | ||
| 31 | |||
| 5 | JohnMcPherson | 32 | __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 successfully converted. |

| 1 | perry | 40 | |
| 5 | JohnMcPherson | 41 | __AF_INET6__ does not recognize IPv4 addresses. An explicit IPv6-mapped IPv4 address must be supplied in ''src'' instead. |
