In WS2tcpip.h, this api inet_pton is defined:

#if (NTDDI_VERSION >= NTDDI_VISTA)
WINSOCK_API_LINKAGE
INT
WSAAPI
inet_pton(
    _In_                                      INT             Family,
    _In_                                      PCSTR           pszAddrString,
    _When_(Family == AF_INET, _Out_writes_bytes_(sizeof(IN_ADDR)))
    _When_(Family == AF_INET6, _Out_writes_bytes_(sizeof(IN6_ADDR)))
                                              PVOID           pAddrBuf
    );
