bind(p1) public

Binds to the given struct sockaddr.

Parameter

  • server_sockaddr - the struct sockaddr contained in a string

Example

require 'socket'
include Socket::Constants
socket = Socket.new( AF_INET, SOCK_STREAM, 0 )
sockaddr = Socket.pack_sockaddr_in( 2200, 'localhost' )
socket.bind( sockaddr )

Unix-based Exceptions

On unix-based based systems the following system exceptions may be raised if the call to bind fails:

  • Errno::EACCES - the specified sockaddr is protected and the current user does not have permission to bind to it

  • Errno::EADDRINUSE - the specified sockaddr is already in use

  • Errno::EADDRNOTAVAIL - the specified sockaddr is not available from the local machine

  • Errno::EAFNOSUPPORT - the specified sockaddr isnot a valid address for the family of the calling socket

  • Errno::EBADF - the sockaddr specified is not a valid file descriptor

  • Errno::EFAULT - the sockaddr argument cannot be accessed

  • Errno::EINVAL - the socket is already bound to an address, and the protocol does not support binding to the new sockaddr or the socket has been shut down.

  • Errno::EINVAL - the address length is not a valid length for the address family

  • Errno::ENAMETOOLONG - the pathname resolved had a length which exceeded PATH_MAX

  • Errno::ENOBUFS - no buffer space is available

  • Errno::ENOSR - there were insufficient STREAMS resources available to complete the operation

  • Errno::ENOTSOCK - the socket does not refer to a socket

  • Errno::EOPNOTSUPP - the socket type of the socket does not support binding to an address

On unix-based based systems if the address family of the calling socket is Socket::AF_UNIX the follow exceptions may be raised if the call to bind fails:

  • Errno::EACCES - search permission is denied for a component of the prefix path or write access to the socket is denided

  • Errno::EDESTADDRREQ - the sockaddr argument is a null pointer

  • Errno::EISDIR - same as Errno::EDESTADDRREQ

  • Errno::EIO - an i/o error occurred

  • Errno::ELOOP - too many symbolic links were encountered in translating the pathname in sockaddr

  • Errno::ENAMETOOLLONG - a component of a pathname exceeded NAME_MAX characters, or an entired pathname exceeded PATH_MAX characters

  • Errno::ENOENT - a component of the pathname does not name an existing file or the pathname is an empty string

  • Errno::ENOTDIR - a component of the path prefix of the pathname in sockaddr is not a directory

  • Errno::EROFS - the name would reside on a read only filesystem

Windows Exceptions

On Windows systems the following system exceptions may be raised if the call to bind fails:

  • Errno::ENETDOWN– the network is down

  • Errno::EACCES - the attempt to connect the datagram socket to the broadcast address failed

  • Errno::EADDRINUSE - the socket’s local address is already in use

  • Errno::EADDRNOTAVAIL - the specified address is not a valid address for this computer

  • Errno::EFAULT - the socket’s internal address or address length parameter is too small or is not a valid part of the user space addressed

  • Errno::EINVAL - the socket is already bound to an address

  • Errno::ENOBUFS - no buffer space is available

  • Errno::ENOTSOCK - the socket argument does not refer to a socket
