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.
