The main motivation for this is to have sinergy with flags parsing, currently
flags for a sockaddr returns a net.Host_Or_Endpoint, but we can't just dial
from it since there isn't a variant.
Consider the following:
```
Options :: struct {
target: net.Host_Or_Endpoint `args:"pos=0,required" usage:"host:port"`,
}
before :: proc() -> (sock: net.TCP_Socket, err: net.Network_Error) {
opt: Options
flags.parse_or_exit(&opt, os.args)
switch t in opt.target {
case net.Host:
sock, err = net.dial_tcp(t.hostname, t.port)
case net.Endpoint:
sock, err = net.dial_tcp(t)
}
return
}
after :: proc() -> (sock: net.TCP_Socket, err: net.Network_Error) {
opt: Options
flags.parse_or_exit(&opt, os.args)
sock, err = net.dial_tcp(opt.target)
return
}
```
For completion, add dial_tcp_from_host() and define the upper functions in terms
of the newly added ones, cuts one repeated block, now:
from_hostname_and_port_string is parse + from_host_or_endpoint
from_hostname_with_port_override is parse + override + from_host_or_endpoint
from_host is to_endpoint + from_endpoint
from_host_or_endpoint is from_endpoint or from_host
The documentation for `setsockopt(2)` mentioned accept filters for
`EINVAL`, but I've found that it can arise for any manner of invalid
values for setting socket options.
We'll just have to leave this as a generic error.
This is a better default than not having it, since it turns errors that
would be signals into error values instead. We could take these as
options but given that we currently don't I think this at the very least
improves on the status quo.
This condition results in os.EACCESS, which we were translating to Broadcast_Disabled.
This was the case because binding to the broadcast address on a UDP port, without setting the BROADCAST flag, also results in this error.
Given the fact that reserved ports also produce this error, we now check for this condition in net.bind() and translate it to a custom, clearer error:
Privileged_Port_Without_Root.
