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, socklen_t address_len);

DESCRIPTION

       The  bind()  function assigns an address to an unnamed socket.  Sockets created with socket(3XNET) function are initially unnamed. They are
       identified 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.

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

       The socket in use may require the process to have appropriate privileges to use the bind() function.

USAGE

       An application program can retrieve the assigned socket name with the getsockname(3XNET) function.

RETURN VALUES

       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:

       EADDRINUSE	       The specified address is already in use.

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

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

       EBADF		       The socket argument is not a valid file descriptor.

       EFAULT		       The  address argument can not be accessed.

       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.

       ENOTSOCK 	       The socket argument does not refer to a socket.

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

       If the address family of the socket is AF_UNIX, then bind() will fail if:

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

       EDESTADDRREQ	       The address argument is a null pointer.
       EISDIR

       EIO		       An I/O error occurred.

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

       ENAMETOOLONG	       A component of a pathname exceeded NAME_MAX characters, or an entire pathname exceeded PATH_MAX characters.

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

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

       EROFS		       The name would reside on a read-only filesystem.

       The bind() function may fail if:

       EACCES		       The  specified  address	is  protected, and {PRIV_NET_PRIVADOR} is not asserted in the effective set of the current
			       process.

       EINVAL		       The address_len 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 PATH_MAX.

       ENOBUFS		       Insufficient resources were available to complete the call.

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