Subject: Provide a function for closing all of the listeners.
X-Git-Tag: 2.3.0~3085
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d6f8c966b0517072156f226955c29122190cc723;p=thirdparty%2Fapache%2Fhttpd.git

Provide a function for closing all of the listeners.

  * This is useful for properly implementing a graceful stop and restart
    where we want child processess to be able to carry on serving a request
    but "de-listen" from a port. So that another instance entirely can be
    started in our place, or to unbind from a "Listen" directive an admin
    has removed from the configuration.
