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
bind() 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. bind() requests that the name pointed to by name be assigned to the socket. RETURN VALUES
If the bind is successful, 0 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: 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. EINVAL The socket is already bound to an address. 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. ATTRIBUTES

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 byus- ing unlink(2). The rules used in name binding vary between communication domains. SunOS 5.10 20 Feb 2003 bind(3SOCKET)
