Synopsis


                ipv4_address
host_ipv4_address() noexcept;

Declared in file <src/url_view_base.cpp> at line 367

Description

If the host type is host_type::ipv4, this function returns the address as a value of type ipv4_address. Otherwise, if the host type is not an IPv4 address, it returns a default-constructed value which is equal to the unspecified address "0.0.0.0".

Example


assert( url_view( "http://127.0.0.1/index.htm?user=win95" ).host_ipv4_address() == ipv4_address( "127.0.0.1" ) );

Complexity

Constant.

Exception Safety

Throws nothing.

BNF


IPv4address = dec-octet "." dec-octet "." dec-octet "." dec-octet

dec-octet   = DIGIT                 ; 0-9
            / %x31-39 DIGIT         ; 10-99
            / "1" 2DIGIT            ; 100-199
            / "2" %x30-34 DIGIT     ; 200-249
            / "25" %x30-35          ; 250-255
