  .Dt BIND 2
  .Os
  .Sh NAME
  .Nm bind
  .Nd bind a name to a socket
  .Sh SYNOPSIS
  .In sys/socket.h
  .Ft int
  .Fn bind "int s" "const struct sockaddr *name" "socklen_t namelen"
  .Sh DESCRIPTION
  .Fn bind
  assigns a name to an unnamed socket.
  When a socket is created with
  .Xr socket 2 ,
  it exists in a name space (address family) but has no name assigned.
  .Fn bind
  requests that
  .Fa name
  be assigned to the socket.
  .Fa namelen
  indicates the amount of space pointed to by
  .Fa name ,
  in bytes; the
  .Fa sa_len
  member of
  .Fa name
  is ignored.
  .Sh NOTES
  Binding a name in the
  .Ux Ns -domain
  creates a socket in the file system that must be deleted by the caller
  when it is no longer needed (using
  .Xr unlink 2 ) .
  .Pp
  The rules used in name binding vary between communication domains.
  Consult the manual entries in section 4 for detailed information.
  .Sh RETURN VALUES
  .Rv -std
  .Sh ERRORS
  The
  .Fn bind
  function will fail if:
  .Bl -tag -width Er
  .It Bq Er EBADF
  .Fa s
  is not a valid descriptor.
  .It Bq Er ENOTSOCK
  .Fa s
  is not a socket.
  .It Bq Er EADDRNOTAVAIL
  The specified address is not available from the local machine.
  .It Bq Er EADDRINUSE
  The specified address is already in use.
  .It Bq Er EINVAL
  The socket is already bound to an address, or
  .Fa namelen
  is not a valid length for the supplied address.
  .It Bq Er EAFNOSUPPORT
  The family of the socket and that requested in
  .Va name->sa_family
  are not equivalent.
  .It Bq Er ENOBUFS
  Insufficient buffer space is available.
  .It Bq Er EACCES
  The requested address is protected, and the current user
  has inadequate permission to access it.
  .It Bq Er EFAULT
  The
  .Fa name
  parameter is not in a valid part of the user address space.
  .El
  .Pp
  The following errors are specific to binding names in the
  .Ux Ns -domain .
  .Bl -tag -width Er
  .It Bq Er ENOTDIR
  A component of the path prefix is not a directory.
  .It Bq Er ENAMETOOLONG
  A component of a pathname exceeded
  .Dv NAME_MAX
  characters, or an entire pathname (including the terminating NUL)
  exceeded
  .Dv PATH_MAX
  bytes.
  .It Bq Er ENOENT
  A prefix component of the pathname does not exist.
  .It Bq Er ELOOP
  Too many symbolic links were encountered in translating the pathname.
  .It Bq Er EIO
  An I/O error occurred while making the directory entry or allocating the inode.
  .It Bq Er EROFS
