|
Validate that all values passed are valid IPv6 addresses.
|
|
Fail compilation if any value fails this check.
|
|
|
|
The following values will pass:
|
|
|
|
$my_ip = "3ffe:505:2"
|
|
validate_ipv6_address(1)
|
|
validate_ipv6_address($my_ip)
|
|
validate_bool("fe80::baf6:b1ff:fe19:7507", $my_ip)
|
|
|
|
The following values will fail, causing compilation to abort:
|
|
|
|
$some_array = [ true, false, "garbage string", "1.2.3.4" ]
|
|
validate_ipv6_address($some_array)
