6 bind - bind a name to a socket

9 #include <sys/types.h>
10 #include <sys/socket.h>
11
12 bind(s, name, namelen)
13 int s;
14 struct sockaddr *name;
15 int namelen;
16
18 Bind assigns a name to an unnamed socket. When a socket is created
19 with socket(2) it exists in a name space (address family) but has no
20 name assigned. Bind requests that name be assigned to the socket.
21
23 Binding a name in the UNIX domain creates a socket in the file system
24 that must be deleted by the caller when it is no longer needed (using
25 unlink(2)).
26
27 The rules used in name binding vary between communication domains.
28 Consult the manual entries in section 4 for detailed information.
29
31 If the bind is successful, a 0 value is returned. A return value of -1
32 indicates an error, which is further specified in the global errno.
33
35 The bind call will fail if:
36
37 [EBADF] S is not a valid descriptor.
38
39 [ENOTSOCK] S is not a socket.
40
41 [EADDRNOTAVAIL] The specified address is not available from the
42 local machine.
43
44 [EADDRINUSE] The specified address is already in use.
45
46 [EINVAL] The socket is already bound to an address.
47
48 [EACCES] The requested address is protected, and the current
49 user has inadequate permission to access it.
50
51 [EFAULT] The name parameter is not in a valid part of the
52 user address space.
53
54 The following errors are specific to binding names in the UNIX domain.
55
56 [ENOTDIR] A component of the path prefix is not a directory.
57
58 [EINVAL] The pathname contains a character with the high-order
59 bit set.
60
61 [ENAMETOOLONG] A component of a pathname exceeded 255 characters, or an
62 entire path name exceeded 1023 characters.
63
64 [ENOENT] A prefix component of the path name does not exist.
65
66 [ELOOP] Too many symbolic links were encountered in translating
67 the pathname.
68
69 [EIO] An I/O error occurred while making the directory entry
70 or allocating the inode.
71
72 [EROFS] The name would reside on a read-only file system.
73
74 [EISDIR] A null pathname was specified.
75
77 connect(2), listen(2), socket(2), getsockname(2)
