NAME
     bind - bind a name to a socket

SYNOPSIS
     cc [flag ...] file ... -lxnet [library ...]

     #include <sys/socket.h>

     int bind(int socket, const struct sockaddr *address,
              sizet addresslen);

DESCRIPTION
     The bind function assigns an address to an unnamed socket. Sockets
     created with socket function are initially unnamed; they are identi-
     fied only by their address family.

     The function takes the following arguments:

     socket            Specifies the file descriptor of the socket to be
                       bound.

     address           Points to a sockaddr structure containing the
                       address to be bound to the socket. The length and
                       format of the address depend on the address family
                       of the socket.

     addresslen       Specifies the length of the sockaddr structure
                       pointed to by the address argument.

RETURN VALUE
     Upon successful completion, bind returns 0. Otherwise, -1 is returned
     and errno is set to indicate the error.

ERRORS
     The bind function will fail if:

     EBADF             The socket argument is not a valid file descriptor.

     ENOTSOCK          The socket argument does not refer to a socket.

     EADDRNOTAVAIL     The specified address is not available from the
                       local machine.

     EADDRINUSE        The specified address is already in use.

     EINVAL            The socket is already bound to an address, and the
                       protocol does not support binding to a new address;
                       or the socket has been shut down.

     EACCES            The specified address is protected and the current
                       user does not have permission to bind to it.

bind(3N-xs)                   (X/OPEN SOCKETS)                  bind(3N-xs)

     EAFNOSUPPORT      The specified address is not a valid address for the
                       address family of the specified socket.

     EOPNOTSUPP        The socket type of the specified socket does not
                       support binding to an address.

     If the address family of the socket is AFUNIX, then bind will fail
     if:

     EDESTADDRREQ or EISDIR
                       The address argument is a null pointer.

     EACCES            A component of the path prefix denies search permis-
                       sion, or the requested name requires writing in a
                       directory with a mode that denies write permission.

     ENOTDIR           A component of the path prefix of the pathname in
                       address is not a directory.

     ENAMETOOLONG      A component of a pathname exceeded {NAMEMAX} char-
                       acters, or an entire pathname exceeded {PATHMAX}
                       characters.

     ENOENT            A component of the pathname does not name an exist-
                       ing file or the pathname is an empty string.

     ELOOP             Too many symbolic links were encountered in
                       translating the pathname in address.

     EIO               An I/O error occurred.

     EROFS             The name would reside on a read-only file system.

     The bind function may fail if:

     EINVAL            The addresslen argument is not a valid length for
                       the address family.

     EISCONN           The socket is already connected.

     ENAMETOOLONG      Pathname resolution of a symbolic link produced an
                       intermediate result whose length exceeds {PATHMAX}.

     ENOBUFS           Insufficient resources were available to complete
                       the call.

     ENOSR             There were insufficient STREAMS resources for the
                       operation to complete.

APPLICATION USAGE
     An application program can retrieve the assigned socket name with the
     getsockname function.
