host_ipv6_address

Return the host IPv6 address

Synopsis

ipv6_address host_ipv6_address() noexcept;

Declared in file <src/authority_view.cpp> at line 247

Description

If the host type is host_type::ipv6, this function returns the address as a value of type ipv6_address. Otherwise, if the host type is not an IPv6 address, it returns a default-constructed value which is equal to the unspecified address "0:0:0:0:0:0:0:0".

Example

assert( url_view( "ftp://[::1]/" ).host_ipv6_address() == ipv6_address( "::1" ) );

Complexity

Constant.

Exception Safety

Throws nothing.

BNF
