BIND(3SOCKET) Sockets Library Functions BIND(3SOCKET)

NAME

bind - bind a name to a socket

SYNOPSIS

cc [ flag ... ] file ... -lsocket -lnsl [ library ... ]
#include <sys/types.h>
#include <sys/socket.h>


int bind(int s, const struct sockaddr *name, int namelen);

DESCRIPTION

The bind() function assigns a name to an unnamed socket. When a
socket is created with socket(3SOCKET), it exists in a name space
(address family) but has no name assigned. The bind() function
requests that the name pointed to by name be assigned to the socket.

RETURN VALUES

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

ERRORS

The bind() function will fail if:

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


EADDRINUSE
The specified address is already in use.


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


EBADF
s is not a valid descriptor.


EINVAL
namelen is not the size of a valid address for the
specified address family.

The socket is already bound to an address.

Socket options are inconsistent with port
attributes.


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


ENOTSOCK
s is a descriptor for a file, not a socket.


The following errors are specific to binding names in the UNIX
domain:

EACCES
Search permission is denied for a component of the path
prefix of the pathname in name.


EIO
An I/O error occurred while making the directory entry or
allocating the inode.


EISDIR
A null pathname was specified.


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


ENOENT
A component of the path prefix of the pathname in name
does not exist.


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


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

NOTES

Binding a name in the UNIX domain creates a socket in the file system
that must be deleted by the caller when it is no longer needed by
using unlink(2).


The rules used in name binding vary between communication domains.
