Manual page for BIND(2)
bind - bind a name to a socket
SYNOPSIS
#include <sys/types.h>
#include <sys/socket.h>
int bind(s, name, namelen)
int s;
struct sockaddr *name;
int namelen;
DESCRIPTION
bind()
assigns a name to an unnamed socket.
When a socket is created with
socket.2
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 VALUES
bind()
returns:
- 0
-
on success.
- -1
-
on failure and sets
errno
to indicate the error.
ERRORS
- EACCES
-
The requested address is protected, and the current user
has inadequate permission to access it.
- EADDRINUSE
-
The specified address is already in use.
- EADDRNOTAVAIL
-
The specified address is not available from the local machine.
- EBADF
-
s
is not a valid descriptor.
- EFAULT
-
The
name
parameter is not in a valid part of the user
address space.
- EINVAL
-
namelen
is not the size of a valid address for the specified address family.
The socket is already bound to an address.
- 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
path name in
name.
- EIO
-
An I/O error occurred while making the directory entry or allocating the inode.
- EISDIR
-
A null path name was specified.
- ELOOP
-
Too many symbolic links were encountered in translating the path name in
name.
- ENAMETOOLONG
-
The length of the path argument exceeds
{PATH_MAX}.
A pathname component is longer than
{NAME_MAX}
(see
sysconf.2v
while
{_POSIX_NO_TRUNC}
is in effect
(see
pathconf.2v
- ENOENT
-
A component of the path prefix of the path name in
name
does not exist.
- ENOTDIR
-
A component of the path prefix of the path name 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 (using
unlink.2v
The rules used in name binding vary between communication domains.
