The getaddrinfo() function performs the functionality of gethostbyname() and getservbyname() but in a more sophisticated manner. The nodename and servname arguments are either pointers to null-terminated strings or NULL. One or both of these two arguments must be a non-NULL pointer.

The getaddrinfo() function combines the functionality provided by the gethostbyname(3) and getservbyname(3) functions into a single interface, but unlike the latter functions, getaddrinfo() is reentrant and allows programs to eliminate IPv4-versus-IPv6 dependencies. The addrinfo structure used by getaddrinfo() contains the following fields: getaddrinfo (Socket) - APIdock This method corresponds closely to the POSIX.1g getaddrinfo() definition. Parameters. host is a host name or an address string (dotted decimal for IPv4, or a hex string for IPv6) for which to return information. A nil is also allowed, its meaning depends on flags, see below. www.msdn.microsoft.com www.msdn.microsoft.com

The getaddrinfo_a() function performs the same task as getaddrinfo(3), but allows multiple name look-ups to be performed asynchronously, with optional notification on completion of look-up operations.

Launching puma with webpack-dev-server within foreman give me the following error: linux - getaddrinfo: command not found - Server Fault getaddrinfo is a library function in the standard C library, not a command line tool. So trying to execute it is not quite the right path to a solution.
