normalize_addr_short(string
addr
)- Description
Normalizes a formatted IPv6 address to a canonical shortest form.
addr
is parsed according to the hexadecimal"x:x:x:x:x:x:x:x"
syntax or any of its shorthand varieties (see RFC 2373 section 2.2).The returned address is normalized as follows: The longest sequence of zeroes is shortened using "::". If there are several of equal length then the leftmost is shortened. All hexadecimal letters are lower-case. There are no superfluous leading zeroes in the fields.
Zero is returned if
addr
is incorrectly formatted.- See also
