u64 socket_connect(String host, u16 port)

:params
host : IPv4 address (for example `127.0.0.1`), as a dotted-quad string
port : port number
return value : the socket handle

:see
>socket

:content
Opens a socket connection to the given `host` and `port`.

The returned socket handle is then used with `socket_read()`, `socket_write()`, and `socket_close()`. Currently this helper accepts IPv4 dotted-quad addresses in socket calls and does not perform hostname resolution.

:example
u64 fd = socket_connect("127.0.0.1", 80);
print(fd != 0 ? "connected to the local server" : "connect failed", "\n");
socket_close(fd);
