bind(3XNET) X/Open Networking Services Library Functions bind(3XNET)NAMEbind - 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 privi‐
leges 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 filesys‐
tem.
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 com‐
plete the call.
ENOSR There were insufficient STREAMS resources for
the operation to complete.
