bind(3N) UNIX System V bind(3N)
NAME
bind - bind a name to a socket
SYNOPSIS
#include <sys/types.h>
int bind(int s, caddrt name, int namelen);
DESCRIPTION
bind assigns a name to an unnamed socket. When a socket is created with
socket, it exists in a name space (address family) but has no name
assigned. bind requests that the name pointed to by name be assigned to
the socket.
RETURN VALUE
If the bind is successful, a 0 value is returned. A return value of -1
indicates an error, which is further specified in the global errno.
ERRORS
The bind call will fail if:
EBADF s is not a valid descriptor.
ENOTSOCK s is a descriptor for a file, not a socket.
EADDRNOTAVAIL The specified address is not available on the local
machine.
EADDRINUSE The specified address is already in use.
EINVAL namelen is not the size of a valid address for the
specified address family.
EINVAL The socket is already bound to an address.
EACCES The requested address is protected and the current
user has inadequate permission to access it.
ENOSR There were insufficient STREAMS resources for the
operation to complete.
The following errors are specific to binding names in the UNIX domain:
ENOTDIR A component of the path prefix of the pathname in
name is not a directory.
ENOENT A component of the path prefix of the pathname in
name does not exist.
EACCES Search permission is denied for a component of the
path prefix of the pathname in name.

ELOOP Too many symbolic links were encountered in
translating the pathname in name.
EIO An I/O error occurred while making the directory
entry or allocating the inode.
EROFS The inode would reside on a read-only file system.
EISDIR A null pathname was specified.

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 [see
unlink(2)].
The rules used in name binding vary between communication domains.
The type of address structure passed to bind depends on the address
family. UNIX domain sockets (address family AFUNIX) require a
socketaddrun structure as defined in sys/un.h; Internet domain sockets
(address family AFINET) require a sockaddrin structure as defined in
netinet/in.h. Other address families may require other structures. Use
the structure appropriate to the address family; cast the structure
address to a generic caddrt in the call to bind and pass the size of the
structure in the namelen argument.
