EventDnsBase::__construct — Constructs EventDnsBase object
Constructs EventDnsBase object.
base
Event base.
initialize
If initialize is true,
it attempts to use the underlying operating system defaults to configure
the DNS base senibly.
If it is false, the DNS base is left unconfigured, with no nameservers or options set.
In the latter case the DNS base should be configured manually, e.g. with
EventDnsBase::parseResolvConf().
If initialize is an integer, it must be one of the following flags:
| Flag | 说明 |
|---|---|
EventDnsBase::DISABLE_WHEN_INACTIVE |
Do not prevent the libevent event loop from exiting when we have no active DNS requests. |
EventDnsBase::INITIALIZE_NAMESERVERS |
Process the resolv.conf.
|
EventDnsBase::NAMESERVERS_NO_DEFAULT |
Do not add default nameserver if there are no nameservers in the resolv.conf.
|
If initialize has a type other than
int|bool,
a TypeError is thrown.
If the value of initialize is invalid,
a EventException is thrown.
| 版本 | 说明 |
|---|---|
| PECL event 3.1.3 |
If initialize has a type other than
int|bool,
a TypeError is thrown.
|
| PECL event 3.1.0RC1 |
The type of the initialize parameter has been changed from bool
to mixed. The value can be either bool (preserving the previous meaning)
or one of the following constants:
EventDnsBase::DISABLE_WHEN_INACTIVE,
EventDnsBase::INITIALIZE_NAMESERVERS,
or EventDnsBase::NAMESERVERS_NO_DEFAULT.
