It is not a ios hack,  It compatible with any system that in accordance with the POSIX standards. The second parameter of function getaddrinfo  can accept the port name or a service name. If you give a service name to it it will translate it to a  standard port number.

if this is an IOS hack, it should be ifdef'd?

also i thought we had a policy against putting os bugfixes in our
codebase? although i dislike this policy...

so only 80, 1935 ? rtmp uses some other ports too. 443 etc.

i am not against patch, i hope there is a way to fix this.

do we have any apple contacts to report this bug?
is it possible to use a different getaddrinfo on ios?

thanks for patch.
