gethostbyname(p1)
public
Use Addrinfo.getaddrinfo instead. This method is deprecated for the following reasons:
-
The 3rd element of the result is the address family of the first address. The address families of the rest of the addresses are not returned.
-
Uncommon address representation: 4/16-bytes binary string to represent IPv4/IPv6 address.
-
gethostbyname() may take a long time and it may block other threads. (GVL cannot be released since gethostbyname() is not thread safe.)
-
This method uses gethostbyname() function already removed from POSIX.
This method obtains the host information for hostname.
p Socket.gethostbyname("hal") #=> ["localhost", ["hal"], 2, "\x7F\x00\x00\x01"]
