DESCRIPTION
ip6_fmt reads the char[16] IPv6 address and returns a compactified
hexadecimal IPv6 address string fe80::fefe.
ip6_fmt_flat reads the char[16] IPv6 address and returns all
hexadecimal IPv6 address labels as string fe80:0000:....:fefe.
ip6_scan reads a compactified IPv6 address string fe80::fefe and
converts it to the char[16] IPv6 address.
ip6_scan_flat reads an uncompressed IPv6 address als hexadecimal string
and returns it's char[16] IPv6 address.
ip6_scanbracket reads a compactified IPv6 address string enclosed in
brackets [fe80::fefe] removes the brackets and calls ip6_scan on the
result.
ip6_ifscan reads the compactified IPv6 address string appended with the
interface_name fe80::fefe/eth0 returns ifname and calls ip6_scan for
the (stripped) IPv6 address.
ip6_cidr reads the compactified CIDR IPv6 address string fe80::fefe/64
determines the prefix as integer plen and calls ip6_scan. If no prefix
is identfied, it returns 128.
ip6_bytestring reads the IPv6 address given as char[16] while returning
the 'bytestring' representation 1001001.... up to the given prefix
length plen.
RETURN CODES
The ip(6)* programs return the number of bytes processed.
ip6_bytestring returns negative numbers on failure.
