constexpr address_v4 make_address_v4(const address_v4::bytes_type& bytes);
Returns: address_v4(bytes).
constexpr address_v4 make_address_v4(address_v4::uint_type val);
Returns: address_v4(val).
constexpr address_v4 make_address_v4(v4_mapped_t, const address_v6& a);
Returns: An address_v4 object corresponding to the IPv4-mapped IPv6 address, as if computed by the following method:
address_v6::bytes_type v6b = a.to_bytes(); address_v4::bytes_type v4b(v6b[12], v6b[13], v6b[14], v6b[15]); return address_v4(v4b);
Remarks: bad_address_cast if a.is_v4_mapped() is false.
address_v4 make_address_v4(const char* str);
address_v4 make_address_v4(const char* str, error_code& ec) noexcept;
address_v4 make_address_v4(const string& str);
address_v4 make_address_v4(const string& str, error_code& ec) noexcept;
address_v4 make_address_v4(string_view str);
address_v4 make_address_v4(string_view str, error_code& ec) noexcept;
Effects: Converts a textual representation of an address into a corresponding address_v4 value, as if by POSIX inet_pton when invoked with address family AF_INET.
Returns: If successful, an address_v4 value corresponding to the string str. Otherwise address_v4().
